I am 56, 175cm and 80 kg. I am diabetic (HbA1c = 6.7) and have elevated cholestrol and low HDL; I am hypertensive. I take medication for all these conditions. My normal heart rate is 78-80. Recently the heart rate has increased to about 90 and sometimes climbs to 120 after i lie down. What could this be due to?
hide you snore at night, have interrupted sleep, excessive daytime sleepiness, if yes it suggests OSA, and it needs a treatment, and it could be a cause for elevated heart rate. Also smoking, low hemoglobin, anxiety, some medicine like inhalers may lead to it. One thyroid test should also be done. Anyway if no reason is found you should monitor your at rest pulse rate and if high need to take medicine beta blocker like Metoprolol. So you should discuss with local doctor. For your cholesterol you should avoid fatty, sugary diet and regular exercises. Also get tablets like atorvastatin 10 mg bedtime prescribed from local doctor and continue this lifetime since this medicine has got cardio protective effect.
