Frequently asked questions
What is the difference between a heart attack and angina?
Angina is chest pain from reduced blood flow that eases with rest; a heart attack is a blockage causing lasting damage and is an emergency. Sudden severe chest pain needs urgent care.
Can MedDroid read my ECG?
Yes — attach it and MedDroid explains the rate, rhythm and features in plain words. It is educational; a cardiologist confirms on the actual tracing.
