Please be reassured â incomplete right bundle branch block is a very common ECG finding in young, healthy people and in itself it is not dangerous and not fatal. It simply means the electrical impulse travels slightly slower down one branch of the conduction system; in the absence of heart disease it needs no treatment and no restriction of activity. Your cardiologist has already examined you and told you the same, and that opinion, along with a normal examination, carries more weight than the ECG label. What you are actually feeling â palpitations, chest tightness, breathlessness during a panic attack â is anxiety-related, and reading alarming things about the ECG tends to keep the cycle going. Slow breathing exercises, regular sleep, cutting down caffeine, and regular exercise help significantly.
Next Steps
No cardiac treatment is needed for incomplete RBBB alone. Get haemoglobin,
thyroid function and
vitamin D/
B12 checked, as these commonly mimic anxiety symptoms. Seek review promptly only if you develop fainting, chest pain on exertion, or breathlessness on walking. If the anxiety episodes are recurring, they are very treatable â you can book a teleconsult with me on Practo or visit me at Synergy Multispeciality Hospital, Miraj (consultation fee Rs 100) and we will plan it together.
