WitrynaThe first step in managing narrow complex tachycardia is to determine if the patient is hemodynamically stable. Indicators of hemodynamic instability are low blood pressure, shortness of breath, a decrease in consciousness, or chest pain (usually pressure). If the patient is hemodynamically stable, there is more time to evaluate the patient’s ... Witryna9 mar 2024 · Narrow complex tachycardia (QRS<120ms) indicates normal ventricular conduction and therefore a supraventricular source of arrhythmia. As with sinus rhythm, leads V1 and II are helpful to identify flutter waves, which most commonly proceed in a counter-clockwise loop away from lead II (producing inverted flutter waves) and … Witryna3 Differential Diagnosis. 3.1 Narrow-complex tachycardia. 3.2 Wide-complex tachycardia. 4 Evaluation. 5 Management. 5.1 Narrow Regular Tachycardia. 5.2 Narrow Irregular Tachycardia. 5.3 Atrial fibrillation with … coupling transforms
