I've noticed that my resting pulse rate usually hovers around 90, although it can dip slightly below that sometimes. Is this normal for me? Also, I've observed that my pulse rate spikes to around 120 after I eat and take a light walk, like after lunch. Is this something I should be concerned about? Just a month ago, I went for a health check-up, and both the ECG and 2D echo turned out normal. I'd love to get your thoughts on this.

A resting pulse rate of around 90 beats per minute can be considered within the normal range, although it is on the higher side. It is normal for the pulse rate to increase after eating or during physical activity. A pulse rate of around 120 beats per minute while walking after lunch is also within normal limits, especially if you were engaging in mild physical activity. Since your ECG and 2D echo results were normal one month back, it is reassuring that there are no underlying heart conditions causing these pulse rate variations. However, if you continue to have concerns about your pulse rate, it would be advisable to monitor it regularly and consult with your healthcare provider for further evaluation and advice on managing your pulse rate.
