Clinically: Initial treatment of AFlutter is the same, regardless of whether the rotation direction is CW or CCW — so this distinction is not important to the emergency provider ( Cosio — Arrhythmia & EP Review 6(2):55-62, 2017 ). And a Final Tracing. As a final advanced concept — I add one more tracing in Figure-4.
But there are 3 other wide beats in the tachycardia that begins with beat #6 ( = beats #7; 13,14 ). Most Torsades is the result of a pause-dependent effect that predisposes to development of the malignant arrhythmia ( Dohadwala et al — Heart Rhythm Case Rep 3(2):115-119, 2017 ).
This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ). He required multiple defibrillations within a period of a few hours.
The rule of thumb is less accurate, and the risk is higher because a long QT in the presence of bradycardia ("pause dependent" Torsades) predisposes to Torsades. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval. 3) At heart rates below 60, far more caution is due. which is 0.6
Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. 2017 AHA/ACC/HRS guideline for management of patients with ventricular arrhythmias and the prevention of sudden cardiac death. Heart Rhythm, 15(9): 1394-1401. [7]
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. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
There is sinus tachycardia and also a large R-wave in aVR. Drug toxicity , especially diphenhydramine , which has sodium channel blocking effects, and also anticholinergic effects which may result in sinus tachycardia, hyperthermia, delirium, and dry skin. Her temperature was 106 degrees. As part of the workup, she underwent an ECG.
There was never ventricular fibrillation (VF) or ventricular tachycardia (VT), no shockable rhythm. Here is a similar case: Collapse, Ventricular Tachycardia, Cardioverted, Comatose on Arrival. Agitation, Confusion, and Unusual Wide Complex Tachycardia. There is sinus tachycardia at ~115/minute.
This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern. CMAJ 2017 Vassallo SU, Delaney KA, Hoffman RS, et al. What do you think?
