This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I am 24 years old, and my heart is having episodes of rapid, uncontrollable pounding which is giving me shortness of breath and faintness. This has only started recently with my first episode giving me tunnel vision. What should I do?

Hello,

Welcome to icliniq.com.

This can be a cardiac arrhythmia like PSVT (paroxysmal supraventricular tachycardia) or atrial fibrillation, in which heart rate suddenly goes up and also suddenly decreases. Blood pressure falls during these episodes, and one has dizziness, fainting, blackouts, sometimes syncope. ECG (electrocardiography) done during episodes will show abnormality. You may need 24 hour Holter monitoring if ECG is not informative. So, visit a nearby cardiologist for these investigations. Till the time your evaluation is complete, you can ask your local doctor for tablet Metoprolol XL 25 mg once a day.
