Paroxysmal ventricular tachycardia

This code represents a form of ventricular tachycardia characterized by sudden, recurrent episodes of rapid heartbeats originating from the ventricles. These paroxysmal events are typically self-limiting but can be sustained and potentially life-threatening.

Apply this code when documentation clearly indicates recurrent, episodic ventricular tachycardia. This diagnosis is supported by ECG findings demonstrating three or more consecutive ventricular beats at a rate exceeding 100 bpm, with a sudden onset and termination.

• Differentiate from sustained ventricular tachycardia (427.1) if the paroxysmal nature is not explicitly documented.
• Consider sequencing with underlying cardiac conditions (e.g., ischemic heart disease, cardiomyopathy) if present and contributing.
• Ensure documentation specifies "paroxysmal" to avoid confusion with other forms of ventricular arrhythmias.
