From afar, there is gross tachycardia, cadence irregularities, and narrow QRS complexes that may, or may not, be Sinus in origin; and finally – a cacophony of wide complexes that might very well be ventricular in origin. McLaren : We’ve answered the first question – Sinus Tachycardia with episodic runs of wide QRS (RBBB morphology) and PVC’s.

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. Learning points 1] Acute Coronary Syndrome has many shades of clinical manifestation.

A coronary angiogram was done that did not show significant coronary artery disease. But there are 3 other wide beats in the tachycardia that begins with beat #6 ( = beats #7; 13,14 ). Post ROSC the patient was alert and cooperative. Echocardiography showed apical ballooning with hypokinesis.

Ct coronary angiogram showed normal coronary arteries. Smith note: I think CT coronary angiogram is reasonable with the elevated troponins and symptoms. T-wave inversions and dynamic ST elevation Tachycardia, hyperthyroid, and ST elevation. He was diagnosed with mild AKI which resolved. What is it?

We investigated the incidence of an acutely occluded coronary in patients presenting with STE-aVR with multi-lead ST depression. All electrocardiograms (ECGs) and coronary angiograms were blindly analyzed by experienced cardiologists. A slightly prolonged QTc ( although this is difficult to assess given the tachycardia ).

I find AV dissociation in VT to be very difficult to differentiate from artifact, as there are always random blips on tachycardia tracings. Cardiology was consulted and the patient underwent coronary angiogram which showed diffuse severe three-vessel disease. Coronary angiogram shows diffuse severe three-vessel disease.

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. 3) Anemia, or poisons of hemoglobin such as methemoglobin or CO 4) Fixed coronary stenosis that limits flow.

Patients with BrS can be asymptomatic or present with symptoms secondary to polymorphic ventricular tachycardia or ventricular fibrillation. The routine laboratory results, imaging study, coronary angiogram, and echocardiogram (ECG) were normal. The patient did not have underlying diseases.

There is appreciable STE aVR with near-global STD that appropriately maximizes in Leads II and V5, and thus suggesting a circumstance of generic, diffusely populated, circumferential subendocardial ischemia versus occlusive coronary thrombus. [1] It’s judicious, then, to arrange for coronary angiogram. Does the ECG normalize?

The status of the patients chest pain at this time is unknown : EKG 1, 1300: There is sinus tachycardia and artifact of low and high frequency. However, there is also significant tachycardia , with heart rate of 116, and known hypoxia. Acute coronary occlusion and acute pulmonary edema can coexist.

Angiogram Door to balloon time was 120 minutes (much too long) because of time taken for a CT. Coronary angiogram showed 100% mid LAD occlusion for which she received a DES with excellent angiographic result. It was not SCAD (coronary dissection) Highest troponin I was 37,000 ng/L, but it was not measured to peak.

One big chunk of ACS-UA is secondary UA where there is increased demand as in stable angina with tachycardia*. we can witness menacingly deep resting ST depression with absolutely no thrombotic process going on in the coronary. Mind you, even a coronary angiogram will not bail you out in terms of decision-making and risk prediction.

During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). CT coronary angiogram showed a hypoplastic RCA and dominant LCx. This patient very likely has some form of idiopathic ventricular tachycardia. No PVCs are seen.
