She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Are you confident there is no ischemia? 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. Is this: 1.

No evidence for ischemia jumps out. Conduction system pacing" is a newer technique that is being studied as a way of delivering more physiologic pacing, typically by inserting a lead into the area of the left bundle branch, or the bundle of His. So the most likely rhythm in ECG 1 is ectopic atrial tachycardia.

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. Again, not an expected outcome with diltiazem).

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. Extensive conduction system abnormalities can have various causes (ischemia, genetic, infectious, amyloid, etc). During the next 24 hours, she experienced periods of complete AV block with a ventricular escape rhythm in the 20s.

At about this point in the process — I like to take a closer LOOK at the 12-lead tracing, to ensure there is no acute ischemia or infarction that might need immediate attention. C ASE C onclusion : I lack detailed follow-up from today's case — other than knowing that the Atrial Tachycardia was controlled.

DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology.

We have also shown several cases in which atrial flutter hides true, active ischemia. Tachycardia and ST Elevation. Tachycardia to this degree can cause ST segment changes in several ways.
