I'm really concerned because every few days, I feel my heart beating really strongly, especially when I'm lying down. It's so intense that my whole upper body shakes with each heartbeat. I've had an ECG and an echo, and both came back normal, but these episodes still happen occasionally. What could be causing this? Should I be worried?
It sounds like you may be experiencing palpitations. Since your ECG and echo results came back normal, it's good to rule out any underlying heart conditions. In this case, you can try using a beta-blocker medication such as Metoprolol (brand name: Lopressor) at a low dose of 25mg to help reduce the strength and frequency of your heartbeats. It is important to follow up with your doctor to discuss this option and any potential side effects.
