Circulation, Volume 150, Issue Suppl_1 , Page A4145609-A4145609, November 12, 2024. Electrocardiogram (ECG) and telemetry revealed junctional bradycardia with heart rate in 30s and sinus pauses (5-7 seconds). He was admitted for further workup of bradycardia. Patient did not report any symptoms and was hemodynamically stable.

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. The physiologic reason for this — is thought to be the result of momentarily increased circulation from mechanical contraction arising from the "sandwiched in" QRS complex. She was started on isoprenalin (isoproterenol).

Abnormal readings can signal issues with circulation or lung function, prompting further investigation. Early detection of conditions like AFib, bradycardia, or tachycardia allows patients to address issues before they become critical. Sleep Monitoring Quality sleep is essential for heart health.

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.

Automatic activity refers to enhanced pacemaking function (typically from a non sinus node source), for example atrial tachycardia. Circulation Research , 56 (2), 184–194. Circulation , 63 (2), 333–340. The most common triggered arrhythmia is Torsades de Pointes. Do not treat AIVR. In fact, use of antidyrhythimcs (e.g.,

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

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades.

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.
