A 39-year-old male asked:
When I am asleep, I am suddenly jolted awake with what seems like an extremely strong single heart beat. Extreme chest jolt. What could this mean?

C/W arrhythmia early: heart beat (vs previous heart rate) which is inherently weaker (↓ time for & quantity of blood return into ventricles; resulting in ↓ intensity of heart muscle contraction; both internal heart & split-second brain control), resulting in ↓ intensity of contraction, pump & artery expansion. The following heart beat pumps both usual volume plus additional not pumped by previous, thus more intense.
