I'm really worried about my heart. This morning, I had these palpitations and ended up going to the ER. They ran an ECG and did an echo, which came back normal, but the doctor suggested an ablation. I keep having palpitations even when I'm just climbing the stairs, and now I'm on these Dilzem tablets. Sometimes it feels like my heart actually stops and then starts again. Should I be concerned about this? Is there something serious going on?

It sounds like you are experiencing palpitations and irregular heartbeats. The medication prescribed to you, Dilzem tablet, contains the active ingredient Diltiazem. This medication is a calcium channel blocker that helps to regulate your heart rate and rhythm. The usual dosage for Dilzem in such cases is 120-360 mg per day, divided into 3-4 doses. Feeling like your heart stops and then starts can be concerning, and it is important to follow up with your doctor about this symptom. It could be related to the underlying heart condition that is causing your palpitations. If you continue to experience this sensation, it is recommended to seek medical attention promptly for further evaluation and management.
