Anatomy & Body Systems
Normal Cardiac Conduction Pathway:
-
Sinoatrial (SA) Node: Located in the right atrium near the superior vena cava, the SA node is the heart's natural pacemaker. It fires regularly at 60-100 beats per minute, initiating each heartbeat.
-
Atria: The electrical impulse spreads through the atrial muscle, causing the atria to contract and pump blood into the ventricles.
-
Atrioventricular (AV) Node: Located in the floor of the right atrium near the tricuspid valve, the AV node acts as a "gatekeeper" or electrical relay station. It slows the impulse slightly (approximately 100 ms delay) to allow the ventricles to fill with blood before contracting.
-
His Bundle: The impulse travels from the AV node through the His bundle, which divides into the right and left bundle branches.
-
Purkinje Fibers: These specialized fibers rapidly distribute the electrical impulse throughout the ventricles, causing them to contract and pump blood to the lungs and body.
In SVT:
- AVNRT (AV Node Reentrant Tachycardia): The AV node has two pathways (fast and slow). Under certain conditions, an impulse can travel down one pathway and back up the other, creating a continuous loop.
- AVRT (AV Reentrant Tachycardia): An accessory pathway exists between atria and ventricles. The impulse travels down through the AV node, up through the accessory pathway, and circles repeatedly.
- Atrial Tachycardia: An abnormal focus in the atrial tissue fires rapidly (often 150-200 bpm), overriding the SA node.
- Right Atrium: Upper right chamber receiving deoxygenated blood from the body; location of SA node
- Left Atrium: Upper left chamber receiving oxygenated blood from the lungs
- AV Node: Electrical relay station between atria and ventricles
- Accessory Pathways: Extra electrical connections (like in Wolff-Parkinson-White)
- Coronary Sinus: Vein that runs along the back of the heart, important in SVT mapping
Types & Classifications
By Mechanism (Most Common Classification)
| Type | Mechanism | Prevalence | Characteristics |
|---|---|---|---|
| AVNRT | Reentry within AV node (dual pathways) | 50-60% of SVT | Abrupt onset, 180-200 bpm, retrograde P waves |
| AVRT | Reentry using accessory pathway | 30% of SVT | May be faster (200+ bpm), delta waves if WPW |
| Atrial Tachycardia | Rapid firing from atrial focus | 10% of SVT | Variable rate, P waves before QRS |
AVNRT (AV Node Reentrant Tachycardia):
This is the most common type of SVT. It occurs when there are two electrical pathways within the AV node - a fast pathway and a slow pathway. Normally, the impulse travels down the fast pathway. However, if a premature beat arrives while the fast pathway is still refractory, it may travel down the slow pathway. By the time it reaches the ventricles, the fast pathway may have recovered, allowing the impulse to travel back up to the atria, creating a continuous reentry circuit.
- Typical heart rate: 180-200 bpm
- Usually occurs in people with structurally normal hearts
- More common in women
- Often begins in young adulthood
AVRT (AV Reentrant Tachycardia):
This type uses an accessory pathway - an extra electrical connection between the atria and ventricles that some people are born with. When an impulse travels down through the AV node and back up through the accessory pathway (or vice versa), it creates a reentry circuit. In Wolff-Parkinson-White syndrome, the accessory pathway is visible on ECG as delta waves.
- Typical heart rate: 200-280 bpm
- Can be faster than AVNRT
- May be associated with rapid conduction during atrial fibrillation (dangerous)
- Can be congenital
Atrial Tachycardia:
This occurs when an abnormal focus in the atrial tissue fires rapidly, overriding the SA node. This is less common than AVNRT or AVRT and may be associated with underlying heart disease.
- Typical rate: 150-200 bpm
- P waves visible on ECG
- Often associated with structural heart disease
- May be persistent rather than paroxysmal
| Pattern | Description |
|---|---|
| Paroxysmal | Sudden onset and offset, episodes lasting seconds to hours |
| Persistent | Lasts longer than 30 seconds, may require intervention to stop |
| Incessant | Almost continuous, present most of the time |
| Chronic Reciprocating | Ongoing, may be well-tolerated |
- Typical AVNRT: Narrow QRS, retrograde P waves (often hidden in QRS)
- Atypical AVNRT: Narrow QRS, retrograde P waves after QRS
- Orthodromic AVRT: Narrow QRS, retrograde P waves
- Antidromic AVRT: Wide QRS (pre-excitation)
- Atrial Tachycardia: Narrow QRS, visible P waves before each QRS
Causes & Root Factors
Congenital (Present from Birth):
- Dual AV Node Physiology: The presence of two electrical pathways within the AV node is present from birth but may not manifest until triggered later in life
- Accessory Pathways: Extra electrical connections between atria and ventricles (may be silent or cause WPW)
- Ectopic Atrial Focus: An area of atrial tissue with enhanced automaticity
Acquired Factors:
- Scar Tissue: From previous heart surgery or heart attack can create abnormal circuits
- Cardiomyopathy: Any condition affecting heart muscle structure
- Valvular Heart Disease: Especially mitral valve disease
- Congenital Heart Disease: Some structural heart abnormalities predispose to SVT
Physiological Triggers:
- Stress (Emotional): Increased sympathetic activation can precipitate episodes
- Exercise: Especially sudden intense exercise in deconditioned individuals
- Dehydration: Electrolyte shifts can affect cardiac electrical stability
- Sleep Deprivation: Fatigue increases sympathetic tone
Dietary Triggers:
- Caffeine: Stimulant that can trigger or worsen SVT
- Alcohol: Especially binge drinking or alcohol sensitivity
- Energy Drinks: High caffeine and stimulant content
- Certain Food Additives: Some individuals are sensitive to specific substances
Medical Triggers:
- Fever: Elevated temperature can lower the threshold for SVT
- Thyroid Overactivity (Hyperthyroidism): Increases cardiac excitability
- Anemia: Reduced oxygen delivery increases cardiac workload
- Lung Disease: Can affect cardiac function and trigger arrhythmias
- Medications: Some decongestants, asthma medications, and stimulants
At Healers Clinic, we recognize that emotional and psychological factors often play a significant role:
- Anxiety and Stress: Chronic stress increases sympathetic nervous system activity
- Panic Disorder: Can mimic or trigger SVT
- Emotional Upset: Strong emotions can trigger episodes in susceptible individuals
- Anticipatory Anxiety: Fear of having SVT can actually increase episode frequency
Risk Factors
Age:
- SVT can occur at any age, but most commonly presents in young adulthood (20-40 years)
- AVNRT typically presents between ages 20-40
- AVRT can present in childhood (WPW) or later in life
Gender:
- Women are approximately 2 times more likely than men to develop AVNRT
- This may be related to hormonal influences on cardiac electrical properties
Genetic Factors:
- Some families have predisposition to SVT
- Certain congenital heart conditions run in families
- Accessory pathways may be inherited
Congenital Conditions:
- Wolff-Parkinson-White syndrome (accessory pathway)
- Congenital heart defects
- Ebstein's anomaly
Lifestyle Factors:
- Caffeine Intake: Most common trigger; reducing or eliminating often helps
- Alcohol Consumption: Especially binge drinking
- Smoking: Nicotine stimulates sympathetic nervous system
- Recreational Drugs: Cocaine, amphetamines, and others can trigger dangerous arrhythmias
Medical Factors:
- Thyroid Function: Hyperthyroidism should be controlled
- Electrolyte Balance: Maintain normal potassium and magnesium levels
- Blood Pressure: Control hypertension
- Weight: Obesity increases cardiovascular stress
Behavioral Factors:
- Stress Management: Learning stress reduction techniques
- Sleep Quality: Adequate sleep reduces sympathetic activation
- Exercise Habits: Regular moderate exercise, avoid sudden intense exertion
Our comprehensive evaluation includes:
- Detailed history including triggers and patterns
- Medication and supplement review
- Lifestyle assessment (caffeine, alcohol, sleep, exercise)
- Stress evaluation
- Family history screening
- Advanced diagnostic testing (NLS Screening, Lab Testing)

| Dizziness | Sensation of room spinning (vertigo) | 20-30% |
| Anxiety | Feeling of impending doom or panic | 40-50% |
| Fatigue | Extreme tiredness during or after episode | 30-40% |
| Polyuria | Increased urination during/after prolonged episodes | 25% |
Less Common Symptoms:
- Nausea
- Sweating

Typical Features:
- Abrupt Onset: Episode begins suddenly, often without warning
- Heart Rate: Usually 150-250 bpm (can be faster in AVRT)
- Rhythm: Usually regular (may be slightly irregular)
- Duration: Seconds to hours (typically minutes to hours)
- Termination: Often sudden, sometimes with sensation of "flip" or thump
Pattern Variations:
- Frequent Episodes: Multiple episodes per day or week
- Occasional Episodes: Few episodes per year
- Cluster Episodes: Several episodes in a short period, then none for months
- Single Episode: One episode, never recurs
Warning Signs Before Episodes
Some patients experience premonitory symptoms:
- Sense of anxiety or "something wrong"
- Chest tightness
- Neck pressure
- Quickened pulse at rest
- Fatigue preceding episode
Associated Symptoms
During Episodes:
| Symptom | Significance |
|---|---|
| Polyuria | Increased atrial natriuretic peptide (ANP) release during rapid heart rate |
| Neck Discomfort | Pulsatile flow in jugular veins during AVNRT |
| Chest Pain | Usually due to rapid rate, but must rule out ischemia |
| Dyspnea | Reduced cardiac output at very high rates |
| Syncope | Rare (<5%) but can occur with very rapid rates or structural disease |
Thyroid Disease: Hyperthyroidism can both cause and worsen SVT. Thyroid hormone increases cardiac sensitivity to catecholamines and can lower the threshold for SVT episodes.
Anxiety Disorders: There is significant overlap between SVT and anxiety - both can cause palpitations, tachycardia, and anxiety symptoms. Sometimes it's difficult to determine which came first.
Structural Heart Disease: While most SVT occurs in structurally normal hearts, certain conditions predispose to SVT:
- Mitral valve prolapse
- Cardiomyopathy
- Previous cardiac surgery
- Congenital heart disease
After SVT terminates, patients may experience:
- Fatigue lasting hours to days
- Continued palpitations as sinus rhythm returns
- General malaise
- Relief and resolution of anxiety

FAQ
Q: Is SVT dangerous or life-threatening? A: In the vast majority of cases, SVT is not dangerous or life-threatening. While the rapid heart rate can be alarming, it rarely leads to serious complications in people with structurally normal hearts. However, any new onset SVT should be evaluated to rule out underlying conditions.
Q: Can SVT turn into atrial fibrillation? A: SVT and atrial fibrillation are different heart rhythms. While some people can have both, SVT does not typically "turn into" AFib. However, certain treatments for SVT (like medications) may need to be chosen carefully if AFib is also present.
Q: Can I exercise with SVT? A: Generally, yes - exercise is healthy for most SVT patients. However, you should discuss your specific situation with your physician. Some patients find that intense exercise triggers episodes, while regular moderate exercise may help. Avoid sudden intense exertion if it triggers your SVT.
Q: Will I need a pacemaker for SVT? A: Pacemakers are used for slow heart rhythms (bradycardia), not for fast rhythms like SVT. Treatment options for SVT include medications and catheter ablation.
Q: Can stress trigger SVT episodes? A: Yes, stress is a common trigger for SVT. The stress response increases catecholamines (adrenaline and related hormones), which can lower the threshold for SVT episodes. Stress management techniques, including yoga, meditation, and counseling, can be very helpful.
Q: How is SVT different from a panic attack? A: SVT and panic attacks can both cause rapid heartbeat, palpitations, shortness of breath, and anxiety - making them difficult to distinguish. Key differences: SVT has abrupt onset/offset with very rapid rate (150-250 bpm), while panic attacks often have more gradual onset. An ECG during symptoms can distinguish them. Many patients have both conditions.
Q: Can homeopathy really help with SVT? A: Classical homeopathy works by addressing the individual's constitutional susceptibility to arrhythmias. While it does not "cure" the electrical abnormality, many patients report fewer episodes, reduced anxiety about symptoms, and improved overall wellbeing with homeopathic treatment. It works well as part of an integrative approach.
Q: Will I need to take medication forever? A: Not necessarily. Some patients with infrequent episodes manage with lifestyle modifications and acute techniques only. Others choose to stay on medication long-term. Catheter ablation can be curative, potentially eliminating the need for ongoing medication.
Q: Can SVT be inherited? A: While most SVT is not directly inherited, some forms (particularly those associated with accessory pathways like WPW) can run in families. If you have SVT, it's reasonable to inform family members, but they only need evaluation if they experience symptoms.
