Atrial Flutter Bradycardia Tachycardia

Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered. Nevertheless, the widths of both the QRS complex and the RS duration are similar in both the old ECG and the tachycardia.

Wide-complex tachycardia: VT or aberrant, or "other?" The patient had a history of paroxysmal atrial fibrillation and several cardioversions. A wide-complex tachycardia in an older patient must immediately suggest ventricular tachycardia. Instead, the rate of 150, plus the history of AF, suggested atrial flutter.

Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia. Ventricular tachycardia – more than 7 consecutive complexes originating from ventricles at a rate of > 100 bpm. Usually does not exceed 160 bpm.

RBBB is no longer seen after conversion to sinus rhythm — which supports our suspicion that the intermittent RBBB conduction seen every-other-beat during the tachycardia ( in Figure-1 ) was rate-related. Note that QRS morphology after conversion to sinus rhythm is very similar to QRS morphology of odd-numbered beats during the tachycardia.

If the patient has Abnormal Vital Signs (fever, hypotension, tachycardia, or tachypnea, or hypoxemia), then these are the primary issue to address, as there is ongoing pathology which must be identified. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
