Understanding Paroxysmal Supraventricular Tachycardia (PSVT) and its Management
Paroxysmal Supraventricular Tachycardia (PSVT) is a condition characterized by episodes of rapid heart rate originating above the ventricles. It can be triggered by various factors, including stress, caffeine, alcohol, and physical exertion. Your experience of sudden increases in heart rate, particularly upon waking and moving quickly, suggests that your autonomic nervous system may be playing a significant role in these episodes.
1. Autonomic Nervous System and PSVT: The autonomic nervous system regulates involuntary bodily functions, including heart rate. The sympathetic nervous system, which is activated during stress or physical activity, can lead to an increase in heart rate. Your description of feeling your heart rate spike from 60-70 to 120-130 bpm upon sudden movements indicates a possible overreaction of the sympathetic nervous system. Additionally, your history of panic and anxiety disorders can exacerbate these symptoms, as anxiety can lead to heightened sympathetic activity, further increasing your heart rate.

2. Monitoring with Apple Watch: Using an Apple Watch or similar device to monitor your heart rate and rhythm can be beneficial. These devices can provide real-time data on your heart rate and alert you to any irregularities. However, while they can be useful for tracking trends and episodes, they should not replace professional medical evaluations. If you notice significant changes or recurrent episodes, it’s essential to consult with a healthcare provider for a comprehensive assessment.

3. Management Strategies: Given your history of PSVT and the recent increase in episodes, it’s crucial to have a management plan in place. Here are some strategies that may help:
- Medication: You mentioned taking anti-anxiety medication and heart rhythm medications. It’s important to discuss with your healthcare provider whether a consistent regimen of heart rhythm medication is appropriate for you, especially given your recent episodes. Regular use may help stabilize your heart rate and reduce the frequency of PSVT episodes.


- Lifestyle Modifications: Consider making lifestyle changes that may help manage your symptoms. This includes avoiding known triggers such as caffeine and alcohol, practicing stress-reduction techniques (like mindfulness or yoga), and ensuring adequate hydration and nutrition. Regular exercise can also help, but it’s essential to approach it cautiously, especially if you experience symptoms during workouts.


- Breathing Techniques: When you feel your heart rate increase, practicing deep breathing exercises can help activate the parasympathetic nervous system, which counteracts the sympathetic response and may help lower your heart rate. Techniques such as the Valsalva maneuver (holding your breath and bearing down) can also be effective in terminating an episode of PSVT.

4. Follow-Up Care: Since you mentioned planning to follow up with a major hospital, this is a crucial step. A cardiologist can perform further evaluations, such as an electrocardiogram (ECG) or Holter monitor, to assess your heart's electrical activity over time. They may also discuss the potential for catheter ablation, a procedure that can cure PSVT by targeting the abnormal electrical pathways in the heart.

In summary, your symptoms of PSVT, particularly in relation to your autonomic nervous system and anxiety, warrant careful monitoring and management. Utilizing technology like an Apple Watch can aid in tracking your condition, but it is essential to maintain regular consultations with your healthcare provider to adjust your treatment plan as necessary. By combining medication, lifestyle changes, and stress management techniques, you can work towards reducing the frequency and severity of your PSVT episodes.
