I'm a little concerned about my ECG results. I did one using a portable ECG device and it says "Sinus Rhythm," but Im not sure if that means everything is actually okay. Is this considered clinically normal or should I be worried about something else?

Sinus Rhythm on ECG indicates normal heart rhythm. However, to determine if the ECG is clinically normal, other factors need to be considered such as symptoms, medical history, and physical examination. If there are no other concerning findings, the ECG can be considered normal.

My mom recently had an angioplasty and her doctor originally put her on Abiflo, but now they've switched her to Syscan. Since the switch, she's been having some issues like itching on her lips and face, plus there's some swelling on her left foot. Should we be worried about these side effects?

My dad has artery blockages and we're really confused between angioplasty and bypass surgery - which one would be better for his condition? The doctors gave us both options but we're not sure what to go with

Choice depends on blockage location and risk factors; angioplasty is less invasive, but bypass is better for multiple or complex blocks.
