I'm lying down and my heart rate is around 54, but when I stand up it's 86. Is it normal for the heart rate to be under 60? My echo and TMT tests came back normal, but when I get up from bed, I feel dizzy. Should I be worried or is this something that happens often?
A heart rate of 54 beats per minute when lying down can be normal, especially if you are physically fit or athletic, as lower heart rates are common in these individuals. However, the dizziness you experience when standing up could indicate a condition known as orthostatic hypotension, where your blood pressure drops upon standing, leading to dizziness. It is good that your echocardiogram (echo) and treadmill test (TMT) are normal, but I recommend discussing these symptoms with your healthcare provider. They may suggest additional tests, such as measuring your blood pressure and heart rate changes with position changes, to diagnose and manage the underlying cause of your dizziness.
