Your rapid heartbeat returns after a first procedure, even while taking diltiazem (Delziam) and bisoprolol (Concor Cor). This is not uncommon; heart tissue can sometimes heal and find new electrical pathways. A repeat catheter ablation is actually the most effective, potentially permanent cure for recurrent arrhythmias. Because your team now has a map from your first procedure, a second ablation can target the remaining pathways with even greater precision and high success rates. I highly recommend discussing a repeat procedure with your electrophysiologist, as it offers the best path to long-term, drug-free relief.

A fast heartbeat can happen due to stress, anxiety, or underlying health conditions. Concor COR 2.5 helps keep your heart rate steady. Continue taking it as advised by your doctor and do not stop the medication suddenly without talking to the doctor. Try reducing caffeine, staying hydrated, and sleeping well. If your fast heartbeat becomes frequent, follow up with your doctor.

Food does not affect how this medication is absorbed by your body. The most important thing is to take your tablet at the same time every day to keep the medicine working consistently in your system. If you ever feel dizzy or lightheaded, especially when skipping meals, please let your doctor know.

Pain on the left side of the chest and in the lower right side of the abdomen can occur due to different causes such as muscle strain, gas or acidity, or digestive issues. Sometimes chest discomfort may be related to conditions like Gastroesophageal Reflux Disease, while pain in the lower right abdomen could be due to problems such as Appendicitis or intestinal irritation. However, occasional mild pain may also occur from muscle strain or indigestion. If the pain becomes severe or persistent, seek medical attention for proper evaluation.

Taking a beta-blocker on an 'as-needed' basis can cause your heart rate and blood pressure to fluctuate unpredictably, which can actually trigger a rapid rebound pulse. To keep your heart rhythm steady and safe, bisoprolol needs to maintain a consistent level in your system. Please continue taking your daily dose as prescribed. If you have concerns about how you are feeling, please consult your doctor before making any changes.

Dizziness can happen as your body adjusts to bisoprolol (Concor Cor) lowering your blood pressure, especially when standing up. While less common, changes in taste can also occur. For now, please rise slowly from sitting or lying down, drink plenty of water, and keep a log of your blood pressure if you can. Most importantly, please contact your doctor before making any changes. They can safely check your pressure and adjust your dose if needed. Do not stop taking your medication suddenly.
