The computer called it a normal ECG Algorithm unknown Aside : [There is some "sinus arrhythmia", which is indeed a normal finding. Sinus arrhythmia is sinus rhythm whose rate varies with respiration. If the longest P-P interval is 120 ms greater than the shortest, it is sinus arrhythmia. Burning pain subxiphoid and into throat."

While medical trial of an antiarrhythmic agent can at times be undertaken ( assuming the clinician remains at the bedside throughout the process ) — synchronized cardioversion is often favored for treatment of AFib with WPW, given the exceedingly rapid ventricular response with this arrhythmia. What do YOU see?

There was no evidence of ischemia. In the interest of academic discussion Ill present a nother p erspective on selected aspects this case. We are not told how ischemia has been ruled out in this case. They clearly do not s uggest acute coronary occlusion but they are consistent with ischemia. Hyperkalemia.

Therefore, she underwent temporary pacemaker placement and overdrive pacing at a rate of 90 bpm to keep the heart rate up in order to prevent these PVCs triggering ventricular arrhythmia. Hypokalemia was unlikely because she continued to have ventricular arrhythmia despite of correcting electrolytes. Acute ischemia?

The amiodarone was discontinued and the patient did well. == MY Comment , by K EN G RAUER, MD ( 6/23 /2023 ): == From an academic standpoint — I love WCT ( W ide- C omplex T achycardia ) rhythms. The above said — Dr. Smith's approach to today's arrhythmia highlights a number of important points!

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. In this case, there is diffuse ischemic ST depression of subendocardial ischemia, of course with accompanying reciprocal STE in aVR.

However, he suddenly developed a series of malignant ventricular arrhythmias. Below are printouts of some of the arrhythmias recorded. There is no definite evidence of acute ischemia. (ie, This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation.
