I woke up this morning to a heart rate of over 150. What would cause this?

arrhythmia. Would be a serious condition to rule out, but also dehydration, anemia, hyperthyroidism. Call your doctor to discuss when you should be seen.
see dr. There are several things that can cause a rapid heart rate, ranging from anxiety to more serious cardiac heart rhythm abnormalities. You need to see a cardiologist (heart dr) for an evaluation. Best wishes.

I get high 180 heart rate at night but woke up this morning with a heart rate of 36. What can cause such variability?

Arrhythmia. A heart rate of 180, given your age, is approaching the maximum heart rate that doctor's expect when doing "usual" activities (in this case, exercise) without an underlying disorder. If u get this heart rate while sleeping or resting, then u could have atrial fibrilllation (A-fib) or another arrhythmia. In the morning, ur heart compensates by slowing down to rest (the only way). See a cardiologist. Read more...

Hi resting HR. Elevated sympathetic tone.Would check thyroid functions as hyperthyroidism is associated with elevated heart rate , and check for metanephrines in urine( pheochromocytoma which is associated with hypertension) as well as tilt test for postural tachycardia (POTS) which reflects autonomic regulation. Vanderbilt University has an autonomic research center. 615-322-2318. Read more...

Woke up with racing bpm 98-102, while still in bed. It went back to Normal a min later. I've been having anxiety about my heart rate could this cause?

Many reasons; There are many reasons for a fast heart rate, some are metabolic, some are hormonal, some are secondary to uncontrolled stress and anxiety and some are simply circuitry issues within the heart itself. In young adults suffering from anxiety, and whose symptoms include waking up with a racing heart, it is wise to rule out cardiac issues. Usually with an EKG, and at times thyroid hormone testing.

Anxiety. Remaining focused on this may actually exacerbate it . 102 is a little bit elevated -are you have pounding or fluttering sensation. If you have the latter and it is occurring often - get evaluated. In the meantime- If you can find a quiet place - do so. Breath in slowly & deeply through your nostrils. Fill your lungs with air (but not to the point of discomfort). Hold for a count of five then . Read more...
