Sep 15th, 2020 - Background: Calmodulin mutations are associated with arrhythmia syndromes in humans. Exome sequencing previously identified a de novo mutation in CALM1 resulting in a p.N98S substitution in a patient with sinus bradycardia and stress-induced bidir...

Sep 14th, 2020 - An 84-year-old woman with hypertension, Alzheimer's disease, and chronic kidney disease presented with fever and was diagnosed with corona virus disease 2019 (COVID-19). During the hospitalization, she experienced unexpected sinus bradycardia with...

Aug 27th, 2020 - We present a case of sudden asystole that was elicited via the trigeminocardiac reflex in a patient undergoing surgery for a frontal sinus fracture. Asystole occurred after mild stimulation of the supraorbital nerve during dissection along the sup...

Aug 2nd, 2020 - A 65-year-old woman was referred for catheter ablation in the treatment of persistent tachycardia after surgery for atrial fibrillation and mitral regurgitation. Bi-polar voltage mapping of both atria revealed that severe and extensive atrial fibr...

Jul 28th, 2020 - A 64-year-old man with known coronary disease presented to the hospital with sinus bradycardia, chest pain, and normal cardiac enzymes. During an exercise stress test he developed ventricular fibrillation that spontaneously resolved.

Aug 8th, 2018 - ANSWER The correct interpretation includes marked sinus bradycardia with sinus arrhythmia, biatrial enlargement, and an RSR’ pattern in lead V1 suggestive of right ventricular conduction delay. A heart rate below 60 beats/min is considered sinus b.

Jun 6th, 2018 - ANSWER The correct interpretation includes sinus bradycardia with marked sinus arrhythmia and junctional escape beats, and an intraventricular conduction delay. This type of ECG is not ideal for calculating the ventricular rate via the 30/150/100.

Mar 7th, 2018 - ANSWER The correct interpretation includes sinus bradycardia, marked sinus arrhythmia, junctional escape beats with sinus arrest or a transient atrioventricular (AV) block, and an intraventricular conduction defect. Sinus bradycardia is diagnosed.

Jan 3rd, 2018 - ANSWER The correct interpretation includes marked sinus bradycardia with a second-degree atrioventricular (AV) block (Mobitz I) and occasional junctional escape, left-axis deviation, and evidence of an inferior MI. Poor R-wave progression is also.

Jan 2nd, 2018 - A 96-year-old woman with hypertension, diabetes,    and dementia was found unresponsive in her nursing home and was transferred to the hospital. At presentation to the hospital, her blood pressure was 76/43 mm Hg, heart rate 42 beats per minute, r.
