Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology. Read about Fascicular VT here: Idiopathic Ventricular Tachycardias for the EM Physician Case Continued He was completely stable, so adenosine was administered. See Learning point 1 below.

Here is the ECG: Sinus tachycardia. So the real QT is shorter, but the computer does not mention the U-wave, and the U-wave is as important as the T-wave in predicting cardiac dysrhythmias. IV administration of potassium is indicated when arrhythmias are present or hypokalemia is severe (potassium level of less than 2.5

Is it ventricular tachycardia (VT) due to hyperK or is it a supraventricular rhythm with hyperK? Here are other posts on hyperK, large calcium doses for hyperK, and ventricular tachycardia in hyperK Weakness, prolonged PR interval, wide complex, ventricular tachycardia Very Wide and Very Fast, What is it?

myocardial infarction), arrhythmias, valvular pathology, shunts, or outflow obstructions. Smith comment: In a large randomized trial of dopamine vs. norepinephrine (11) for shock which was published after the above-mentioned recommendations, dopamine had more adverse events (especially severe dysrhythmias, and especially atrial fibrillation).

See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades. Could the dysrhythmias have been prevented? IV administration of potassium is indicated when arrhythmias are present or hypokalemia is severe (potassium level of less than 2.5 If cardiac arrest from hypokalemia is imminent (i.e.,

Here was his ED ECG: There is sinus tachycardia (rate about 114) with nonspecific ST-T abnormalities. An ECG was recorded: This shows a regular narrow complex tachycardia at a rate of about 160. See my quick review of atrial tachycardia below) The tachycardia spontaneously resolved. BP:143/99, Pulse 109, Temp 37.2 °C

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. There was a 0.9% Circulation, 117, 1890–1893. [3]:

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. The most recent and probably best study is this: Canadian Syncope Arrhythmia Risk Score. Vasovagal syncope is generally benign.
