High Heart Rate

Hi:

As reported, tachycardia (heart rate over 100 beats per minute) may/can be part of the body's normal response to fever, stress, anxiety, rapid blood loss, or strenuous exercise (in this situation, it is obviously expected). It also may/can be caused by medical problems/conditions, such as hyperthyroidism, or by an adrenal gland tumor (pheochromocytoma).

In some individuals, tachycardia is the result of a cardiac arrhythmia (a heart-generated abnormality of heart rate or rhythm), blocked or narrowed arteries due to coronary artery disease, or a heart valve abnormality.

Tachycardia may/can also be caused by lung (problems, such as pneumonia or a blood clot in one of the lung's arteries). In other cases, tachycardia can be a side effect of some drugs (prescription and over-the-counter), foods (which includes additives and preservatives), and drinks, including coffee, tea, alcohol and chocolate, tobacco or drugs.

Paroxysmal supraventricular tachycardia (PSVT) usually causes a typically frightening burst in heart rate that begins suddenly and ends suddenly (the "P" in paroxysmal), which can last for just mere seconds, or it can continue on for minutes to hours to days.

Supraventricular tachycardia (SVT) is a broad term that includes various forms of an arrhythmia originating above (supra) the ventricles (the heart's lower pumping chambers). SVT can send the heart into speeds up to 150-200 BPM, and sometimes, even as high as 300 BPM.

ALWAYS be proactive in your health care and treatment. Best of luck down the road of life. Live long and prosper.

Take care

Be a questioning patient. Talk to your doctor and ask questions. Studies show that patients who ask the most questions, and are most assertive, get the best results. Be vigilant and speak up!"
