My wife is 62, and for several weeks has been experiencing high pulse rate (resting - 105 & higher), but her blood pressure is fine. She has had blood tests and an ultrasound (for thyroid); all were normal.
Could there be some other problem?
Here is a link to information on tachycardia (fast heart rate) - http://www.healthcentral.com/encyclopedia/408/729.html.
