I'm a bit worried because my doctor said it's palpitation and my ECG came back normal. At the time, my heart rate was around 100 bpm, and they prescribed me medicine for 10 days. Now it's the fourth day, and I'm noticing my heart rate is sometimes above 100 or in the 90s, but when I wake up, it's around 80 or 78, and at night it's between 67 and 72 when I'm resting. How long do you think it'll take for my heart rate to stabilize back to normal? It's above 90 and sometimes even over 100 in the afternoon before it calms down.
The medication prescribed by your doctor is likely a beta-blocker such as Metoprolol. The usual dosage for heart palpitations is around 25-50mg twice daily. It may take a few weeks for the medication to fully regulate your heart rate. It is important to continue taking the medication as prescribed and follow up with your doctor for any concerns or adjustments to the treatment plan.
