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.

Both of these features make inferior + RV MI by far the most likely ( Pseudoanteroseptal MI is another name for this ) There is also sinus bradycardia and t he patient is in shock with hypotension. A narrow complex bradycardia without any P-waves is also likely to respond to atropine, as it may be a junctional rhythm.

Physiologically — the most commonly observed pattern of AFlutter, known as " Typical " AFlutter — produces 2:1 negative deflections seen in the inferior leads ( as seen in Figure-3 ) — as a result of CCW ( C ounter C lock W ise ) rotation of a fixed reentrant circuit around the tricuspid valve annulus and through the cavo-tricuspid isthmus.

The shortened PR-interval, specifically, proved to be quite beguiling as it swept crews down a differential diagnosis of intermittent accessory pathway syndrome – insomuch as a “syndrome” of recurrent tachycardia to account for the patient’s symptoms. Conversely, some patient’s simply have brisk AVN conduction, which is completely benign.

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. The physiologic reason for this — is thought to be the result of momentarily increased circulation from mechanical contraction arising from the "sandwiched in" QRS complex. She was started on isoprenalin (isoproterenol).

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.
