A Case Report of PR Interval Prolongation Caused by Amlodipine

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Amlodipine is a widely used dihydropyridine calcium channel blocker. Its effects on the cardiac conduction system, especially PR interval prolongation, are rare but clinically important. We report a 25‐year‐old healthy male subject in a clinical trial with baseline first‐degree atrioventricular block (PR interval 230 ms).

Sleep Apnea and Paroxysmal Atrial Fibrillation: Diurnal Patterning of Autonomic Dysfunction and Influence of CPAP Therapy

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Autonomic dysfunction in sleep apnea shows diurnal variation, with stronger associations between SDB severity and HRV during wakefulness than sleep. CPAP therapy induces complex, state‐dependent changes in HRV, suggesting that daytime autonomic alterations may better reflect sustained cardiovascular risk in patients with paroxysmal atrial fibrillation.

The Potential Role of Verapamil Against Fluconazole‐Induced Torsade de Pointes: A Critical Review

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Fluconazole (FZL) is a broad‐spectrum antifungal drug associated with certain serious adverse effects such as polymorphic ventricular arrhythmia due to QT prolongation. Torsade de Pointes (TdP) is a unique type of polymorphic ventricular arrhythmia due to QT prolongation.

Correlation Analysis of 24‐h Minimum Heart Rate Levels and Deceleration Capacity of Heart Rate in Patients With Type 2 Diabetes Mellitus Complicated With Essential Hypertension

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
Sex‐specific 24‐hour minimum heart rate (MHR) stratification in patients with type 2 diabetes mellitus and essential hypertension (T2DM‐EH). Three key findings are shown from subgroup analysis: (1) In the normal MHR group (Group B), advancing age independently predicts reduced deceleration capacity (DC) in both sexes.

Electrophysiologic effects of lidocaine on sinus node and atrium in patients with and without sinoatrial dysfunction. [PDF]

Circulation, 1978
Electrophysiological studies were conducted in 13 patients with normal sinus node function and 14 with sinus node dysfunction before and after intravenous lidocaine. Mean +/- SEM sinus cycle length significantly shortened from 810 +/- 34.3 to 774 +/- 34.3 msec in patients with normal sinus node (P less than 0.001) and from 1061 +/- 67.6 to 1016 +/- 64 ...

Sinus Node Dysfunction and Atrial Fibrillation Associated with Isolated Sinoatrial Node Artery Ectasia

Electronic Journal of General Medicine, 2013
A 74 year-old female patient was admitted to emergency service with a complaints of dizziness and shortness of breath. Complete atrioventricular block was observed and patient was followed up two days with transient transvenous cardiac pacemaker. Afterthat, atrial fibrillation (AF) was progressed and then, coronary angiography was scheduled.
