Then, the current flows to an area known as the bundle of His, which divides into two branches (LBB and RBB) and is the only physiological pathway connecting the atria with the ventricles. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. Usually does not exceed 160 bpm.

She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Answer : The ECG above shows a regular wide complex tachycardia. Said differently, the ECG shows a rather slow ventricular tachycardia with a 2:1 VA conduction. Cardiac output (CO) was being maintained by the tachycardia.

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. VT is the second most common presenting arrhythmia. Vaso or inotropic medications are not harmless, and can precipitate life threatening arrhythmias. She was started on isoprenalin (isoproterenol).

A series of cardiac arrhythmias were seen during the course of her resuscitation — including the interesting arrhythmia shown in the long lead II of Figure-1. PEARL # 5: The simple act of labeling P waves can be invaluable for solving an arrhythmia. Figure-6: Laddergram illustration of the mechanism in today's arrhythmia.

KEY Point: Knowing that the most commonly overlooked arrhythmia is AFlutter — suggests that the BEST way to avoid missing the diagnosis of AFlutter is simply to THINK of AFlutter whenever you have a regular SVT at a rate close to 150/minute ( in which you do not clearly see upright sinus P waves in lead II ). And a Final Tracing.

In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished. 2) Tachycardia to this degree can cause ST segment changes in several ways. Sometimes what appears to be thrombus on angiogram is not actually thrombus.

Abstract Introduction Dual atrioventricular nodal non-reentrant tachycardia (DAVNNT) is a rare and challenging-to-diagnose arrhythmia, without previous reports associating it with a leftward inferior extension (LIE).
