Sinus Rhythm with a Wide QRS Complex with a Run of Ventricular Tachyardia
The rhythm is irregular due to the run of VT. An upright, uniform P wave is seen before the QRS complexes. The QRS complexes are wide. An 8 beat run of VT is seen. During the run of VT there appear to be some dissociated P waves that follow the QRS complexes.
Sinus Rhythm with Ventricular Escape Beats
The rhythm is irregular. An upright P wave is paired with a QRS complex. The PR interval is prolonged. We have multifocal PVCs present. A pause follows the PVCs. The 2nd PVC is followed by some ventricular escape beats.
Multiple and Consecutive PACs with Junctional Escape Beats
The are multiple and consecutive PACs present. It even looks like there is a dropped PAC that follows the 1st,6th, 12th, and 13th complexes. The 1st, 7th, 13th, and 14th complexes look like junctional escape beats.
Sinus Bradycardia with Sinus Arrhythmia
The rhythm is irregular. The difference between the longest and shortest R - R interval is grater than .12 sec. There is one P wave for every QRS complex. The P waves are uniform and upright.
