Is it normal to feel like my heart is pounding really hard when I'm exercising? It feels like my heart's just doing a crazy workout on its own, almost like I can hold it in my hand. When I checked, my heart rate was between 130-140 during a heavy workout. I'm 20 and I do have high cholesterol. I had an ECG and echo done back in May, and everything seemed okay. But when I'm resting, my heart rate drops to about 50 bpm and it doesn't feel heavy at all. It's only happening when I'm working out. Should I be worried and stop doing these intense exercises?

It is not uncommon to feel a heavy heartbeat during intense exercise, especially when your heart rate is elevated. Given your age and previous normal cardiac evaluations, it is less likely to be concerning. However, if you continue to experience discomfort or if the symptoms worsen, it may be advisable to modify your exercise routine. To help manage your symptoms, you can consider taking a beta-blocker medication like Metoprolol at a low dose before exercise to help control your heart rate and reduce the sensation of a heavy heartbeat. It is important to consult with your healthcare provider before starting any new medication. Additionally, focusing on aerobic exercises within your target heart rate zone and gradually increasing intensity may also help in reducing the sensation of a heavy heartbeat during exercise.
