I've been feeling really nervous lately, and my heart starts beating really fast. Sometimes it even feels like there's a tremor in my heart. I'm really worried that my heart might be weak. Can you suggest any treatments or advice to help me with this heart issue?

It sounds like you may be experiencing symptoms of anxiety and panic attacks. To help manage these symptoms, you can try taking Propranolol (Inderal) 10mg to 40mg as needed to help reduce the physical symptoms of anxiety such as fast heart rate and tremors. Additionally, practicing relaxation techniques, deep breathing exercises, and mindfulness meditation can also be helpful in managing anxiety symptoms. If your symptoms persist or worsen, it is important to follow up with a healthcare provider for further evaluation and management.
