TACHYCARDIA
Treatment Guideline Chart

Tachycardia is defined as a cardiac rate that is increased to >100 beats/minute (bpm).

Tachyarrhythmia is used to describe tachycardia in the presence of cardiac rhythm abnormality.

Divided into supraventricular and ventricular tachycardia.

Signs and symptoms related to rapid heart rate are altered sensorium, angina, shortness of breath, myocardial infarction, hypotension and other signs of shock (eg cold clammy skin, low urine output), heart failure or pulmonary congestion.

Tachycardia Management

Control Strategy for Atrial Fibrillation

  • Lenient heart rate (HR) control, compared to strict HR control, may be beneficial in patients with persistent atrial fibrillation who have stable ventricular function (LVEF >0.40) and/or no symptoms related to atrial fibrillation
    • Lenient HR control is defined as achieving resting HR <110 beats per minute (bpm); strict HR control is <80 bpm at rest and HR <110 bpm during a 6-minute walk
    • May be considered as the initial heart rate target for rate control therapy
    • Left ventricular function should be monitored in these patients
  • One trial revealed that in patients with atrial fibrillation and systolic heart failure, routine strategy of rhythm control is not beneficial compared to rate control strategy
