Hello,
With the question “Is the average heart rate increased by 90bpm per night? The doctor's answer is as follows:
The average heart rate of a healthy person is about 60-90 times/minute under normal conditions, without exertion or using stimulants such as coffee, tobacco, alcohol. ,...More than 100 beats/min is considered tachycardia.
Heart rate rises regularly on average 90bpm per evening so that's a bit too fast. However, you will consider other factors such as resting conditions when measuring, psychological state (anxiety, insomnia, ...), stimulant use before or after eating,... Except for objective causes, you should go to a Cardiologist to check, maybe do an electrocardiogram, test electrolytes and thyroid function,...
If you still have questions about increased heart rate, you can go to the hospital. Hospital under Vinmec Health System for further examination and consultation. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
Best regards!
