When atrial tachycardia presents in the setting of atrial flutter or macro-re-entrant atrial tachycardia and the patient is haemodynamically unstable, prompt rhythm management is a clinical priority.
This protocol applies to patients with atrial flutter or macro-re-entrant atrial tachycardia who present with haemodynamic instability — a scenario that demands urgent intervention rather than a wait-and-observe approach.
The recommended first-line intervention involves immediate electrical restoration of rhythm — the complete protocol specifies the precise approach and technical parameters.
