Hello,
You asked whether taking Propranolol 10 mg daily for 6–7 months is safe for someone with PSVT (Paroxysmal Supraventricular Tachycardia), or if it can cause first-degree heart block.
Let me explain:
What is Propranolol?
It's a beta-blocker medicine used to slow down the heart rate, control anxiety-related palpitations, and help prevent episodes of fast heart rhythm like PSVT.
Is it safe for PSVT?
Yes, in many patients, low-dose Propranolol (like 10 mg) is safe and commonly prescribed for PSVT. It helps reduce the frequency of fast heartbeat episodes.
What is first-degree heart block?
It's a mild form of slowed electrical conduction in the heart. Often, it doesn't cause symptoms and doesn't require treatment unless it worsens.
Can Propranolol cause heart block?
In high doses or in sensitive individuals, Propranolol can slow the heart too much or interfere with electrical signals, possibly leading to first-degree heart block.
But 10 mg is a very low dose, and if you are not feeling dizzy, faint, or excessively tired, it’s unlikely to cause a problem.
What to monitor?
Keep checking your pulse rate regularly.
If your pulse drops below 50–55 beats per minute, or if you feel lightheaded or faint, consult your doctor.
A repeat ECG every few months is helpful to make sure the medicine isn't slowing your heart too much.
Conclusion:
Yes, Propranolol 10 mg is generally safe for PSVT patients if prescribed by a doctor. But regular monitoring is important to avoid side effects like slow heart rate or heart block.
Let me know if you have symptoms or want to review your ECG.
