Tachyarrhythmias, defined as abnormal heart rhythms with a ventricular rate of 100 or more beats per minute, are frequently symptomatic and often result in patients seeking care at their provider's office or the emergency department.

You should make an appointment with a healthcare professional if your resting heart rate is consistently higher than 100 bpm or frequently climbs into that range without an obvious cause, such as a vigorous workout.

  • Treatment
  • In anyone who presents with symptomatic tachyarrhythmia, a 12-lead electrocardiogram (ECG) should be obtained while a brief initial assessment of the patient's overall clinical assessment is performed. If the patient is hemodynamically unstable, it may be preferable to obtain only a rhythm strip prior to urgent cardioversion and not wait for a 12-lead ECG. The information acquired from these initial assessments is crucial for the subsequent management of the patient.
  • Recommended specialist
  • If you have Arrhythmia, then a visit to a cardiologist is recommended.
