Adult Tachycardia with Pulse

Tachycardia Defined

Tachycardia is a heart rate that exceeds what would be considered as a normal heart rate. Typically this is a resting heart rate greater than 100 beats per minute (bpm). Tachycardia can be a dangerous condition depending on the type of rhythm and speed of heart rate. This can result in unstable tachycardia where cardiac output is reduced to the point of causing symptoms. If tachycardia becomes symptomatic, then treating the tachyarrhythmia becomes necessary.

Differential Diagnosis

An ECG is used to classify the type of Tachycardia. Tachycardia is either narrow or wide complex based on the QRS complex.
