Controlling Rapid Heartbeats Safely and Effectively

Supraventricular Tachycardia (SVT) is a rapid heart rhythm originating from the upper chambers of the heart (atria). Episodes can start and stop suddenly, causing a heart rate that may exceed 150 beats per minute. SVT can cause symptoms such as palpitations, dizziness, shortness of breath, and chest discomfort.

Causes & Risk Factors:

• Abnormal electrical pathways in the heart
• Heart disease or previous heart surgery
• Stimulants such as caffeine, alcohol, or certain medications
• Stress, illness, or hormonal changes

Diagnosis:

• Electrocardiogram (ECG) to capture heart rhythm during an episode
• Holter or MCT heart monitor for longer-term monitoring
• Electrophysiology (EP) studies to locate abnormal electrical pathways

Treatment & Management:

• Vagal Maneuvers: Techniques such as holding your breath or coughing to help slow the heart rate during an episode.
• Medications: Anti-arrhythmic drugs or beta-blockers to prevent or reduce episodes.
• Catheter Ablation: A minimally invasive procedure to destroy abnormal electrical pathways, often providing a permanent cure.
• Lifestyle Adjustments: Limiting caffeine, alcohol, and stimulants; managing stress; and following heart-healthy habits.
• Regular Monitoring: Follow-up visits and remote monitoring help track heart rhythm and assess treatment effectiveness.

Benefits of Management:

• Reduces frequency and severity of SVT episodes
• Improves energy, daily functioning, and quality of life
• Minimizes risk of more serious heart complications
