This can cause a very rapid heartbeat called ventricular tachycardia. It’s usually caused by scarring from a heart attack or other issues … Read More
We usually don’t notice the beating of our hearts unless something out of the ordinary occurs. Most people occasionally feel the sensation of extra heartbeats.

However, as with any electrical system, sometimes things don’t work exactly as they should.
