A member asked:

Are there any signs in the days / hours before a cardiac arrest? if so what? can lots of pvcs/tachycardia /pounding heartbeat that persists be a sign?

Specializes in surgery

Not specifically: But a variety of symptoms can precede heart attack or arrest and arrythmia is one of those.

Cardiac arrest: In a patient with severe systolic dysfunction, frequent extrasystoles, resting tachycardia, can presage a bad outcome.
