Incidence and Determinants of Implantable Cardioverter‐Defibrillator Therapy With Loss of and Impaired Consciousness

Pacing and Clinical Electrophysiology, Volume 49, Issue 7, Page 925-935, July 2026.
ABSTRACT Introduction Implantable cardioverter‐defibrillators (ICDs) are important in the prevention of sudden cardiac death. However, some appropriate ICD therapies may be considered unnecessary, delivered when patients do not experience symptoms of hemodynamic instability such as loss of consciousness.

Long QT Syndrome Type 5 With Coexisting KCNE1 and RYR2 Variants: A Diagnostic Ambiguity

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Long QT syndrome (LQTS) predisposes to syncope and sudden cardiac death. Type 5 LQTS, linked to KCNE1 variants, is rare. A teenage female presented with recurrent syncope. ECG showed QTc 485 ms. Genetic testing identified KCNE1 and RYR2 variants. Beta‐blockers and ICD prevented events.

Lansoprazole‐Induced Microscopic Colitis Mimicking Anticancer Drug‐Related Diarrhea During Lenvatinib and Pembrolizumab Combination Therapy: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Persistent diarrhea during anticancer therapy may not be attributable to anticancer agents. Our patient presented with diarrhea during lenvatinib–pembrolizumab therapy, likely caused by lansoprazole‐induced microscopic colitis. Even when symptoms closely resemble anticancer drug or immune‐related colitis, drug‐induced colitis due to ...

When sinus tachycardia becomes too much: negative effects of excessive upright tachycardia on cardiac output in vasovagal syncope, postural tachycardia syndrome, and inappropriate sinus tachycardia. [PDF]

, 2019
Background - Upright posture reduces venous return, stroke volume and cardiac output (CO) while causing reflex sinus rate (HR) increase. Yet, in inappropriate sinus tachycardia (IST), postural tachycardia syndrome (POTS), and vasovagal syncope (VVS ...
