I've noticed my heart rate drops to around 41-45 when I'm sleeping, and I'm a bit worried about it. I'm currently taking Ivabradine, 5mg twice a day. During the day, my heart rate is generally between 85-90, and it goes up to 105-110 while I'm walking. I started on Ivabradine because my heart rate would hit 150 with just minimal exertion. Is it normal for my heart rate to drop like that while I'm asleep, or should I be concerned?

A heart rate dropping to 41-45 while sleeping can be concerning, especially if you are already on Ivabradine for high heart rate during the day. Since Ivabradine is a medication that helps lower heart rate, it is important to monitor your heart rate closely. In your case, since your heart rate during the day is around 85-90 and 105-110 while walking after taking Ivabradine, it seems like the medication is working to lower your heart rate effectively. However, a heart rate dropping significantly during sleep may warrant further evaluation. I recommend discussing this with your healthcare provider to determine if any adjustments to your medication dosage or timing are needed. It's important to ensure that your heart rate remains within a safe range even during sleep.

I'm currently on metolar, and I've been wondering if it's okay to have garlic on an empty stomach in the morning. Could it affect the medicine or my health in any way?

Better not to take on empty stomach as it might cause gastritis

I'm feeling really concerned about some symptoms I've been having lately. There's this persistent pain on the left side of my chest and in my left arm, and it's been going on for about four months now. I did a TMT test three months ago and it came back negative, but I'm still worried. I got my ECG and Echo done a few days ago and was told it's anxiety. Could you take a look at the results I've attached and let me know what you think?

"Based on your symptoms and previous tests, it seems like you may be experiencing musculoskeletal pain or nerve-related pain rather than a cardiac issue. You can try taking over-the-counter pain relievers like acetaminophen (Tylenol) for the chest and arm pain. Additionally, you can apply a topical pain relief cream like diclofenac gel to the affected areas. Make sure to follow the recommended dosage instructions on the packaging. If the pain persists, you should follow up with your doctor for further evaluation and management."
