TACHYCARDIA IS A FASTER THAN NORMAL HEART RATE.

HEART RATE IS CONTROLLED BY ELECTRICAL SIGNALS SENT ACROSS HEART TISSUES.

TACHYCARDIA OCCURS WHEN AN ABNORMALITY IN THE HEART PRODUCES RAPID ELECTRICAL SIGNALS.

TACHYCARDIA IS CAUSED BY SOMETHING THAT DISRUPTS THE NORMAL ELECTRICAL IMPULSES, THESE FACTORS INCLUDE:

  • Damage to heart tissues from heart disease.
  • Abnormal electrical pathways in the heart present at birth (congenital).
  • A side effect of medications. Smoking. Fever. High blood pressure.
  • Imbalance of electrolytes, mineral- related substances for conducting electrical impulses.
  • Overactive thyroid (hyperthyroidism). Recreational drugs such as cocaine.
7.

ANY CONDITION THAT PUTS A STRAIN ON THE HEART INCREASE YOUR RISK OF TACHYCARDIA.

  • Heart disease/ family history
  • High blood pressure/ age
  • Smoking/ recreational drugs
  • Heavy alcohol use/ caffeine
  • Psychological stress/ anxiety

TESTS & DIAGNOSIS

ECG/HOLTER MONITOR/ELECTROPHYSIOLOGICAL TEST/ TILT TABLE TEST

TESTS & DIAGNOSIS

  • Electrocardiogram (ECG/EKG) is a primary tool for diagnosing tachycardia.
  • Holter monitor is a portable ECG device worn on a belt or carried in your pocket.
  • Tilt Table Test helps your doctor better understand how tachycardia contributes to fainting spells.
  • Electrophysiological Test is thin, flexible tubes (catheters) tipped with electrodes though blood vessels.
  • Your cardiologist may order additional tests to diagnose an underlying condition that is contributing to tachycardia.

TREATMENTS & DRUGS

  • Ways to slow your heartbeat include: Vagal, maneuvers, meds & cardioversion.
  • Treatments: catheter ablation, meds., a pacemaker, implantable cardioverter-defibrillator.
  • Surgery, preventing blood clots, calcium channel blockers, anti-arrhythmic medications,
  • Diltiazem (cardizem), verapamil (calan), beta blockers, metoprolol (lopressor, toprol), esmolol (brevibloc),
  • Treating the underlying problem may prevent or minimize tachycardia episode.

PREVENTION

  • Exercise & eat a healthy diet. Maintain a healthy weight.
  • Keep blood pressure & cholesterol levels under control.
  • Stop smoking. Don't use recreational drugs. Limit caffeine.
