Atrial Arrhythmias in Cardiac Sarcoidosis—Case Presentation and Systematic Review

Pacing and Clinical Electrophysiology, Volume 48, Issue 12, Page 1384-1395, December 2025.
ABSTRACT Sarcoidosis is a rare idiopathic, multiorgan disease with clinical cardiac involvement in approximately 5% of cases. Diagnosis and management of cardiac sarcoidosis (CS) have mainly focused on impaired LV function, ventricular arrhythmias, and atrio‐ventricular conduction disease.

Comparison of Valvular and Ventricular Function After Right Ventricular, Leadless, Deep Septal, and Left Bundle Branch Area Pacemakers

Pacing and Clinical Electrophysiology, Volume 48, Issue 12, Page 1344-1355, December 2025.
Abstract Introduction Changes in tricuspid regurgitation (TR), mitral regurgitation (MR), and left ventricular ejection fraction (LVEF) are frequently noted after right ventricular apical (RVA) pacemaker implantation but prior studies evaluating whether left bundle branch area (LBBA), deep septal (DS), or leadless pacemaker implantation modify risk for

Multimodal Psychophysiological Assessment Reveals Gastric but Not Cardiac Interoception Deficits in Disorders of Gut‐Brain Interaction

Psychophysiology, Volume 62, Issue 12, December 2025.
ABSTRACT Disorders of Gut‐Brain Interaction (DGBI) are characterized by persistent digestive symptoms in the absence of objectively detectable abnormalities. Visceral hypersensitivity and interoceptive dysfunction are central features of DGBI, yet the specific interoceptive impairments associated with these conditions remain underexplored.

Cardiac conduction system and the electrocardiogram of the common hippopotamus (Hippopotamus amphibius)

Experimental Physiology, Volume 110, Issue 12, Page 1917-1927, December 1, 2025.
Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...

Modeling QRS Complex in dECG

IEEE Transactions on Biomedical Engineering, 2007
It is proposed to model the derivative of electrocardiogram (ECG) signal, which we refer to as dECG, instead of the ECG signal. It is shown that the QRS complex in the dECG signal can be represented in the frequency domain by an all-pole model of appropriate order, the coefficients of the model being determined using the covariance method of linear ...

Wide QRS Complex Tachycardias

Medical Clinics of North America, 2001
Wide QRS complex tachycardia is a common clinical occurrence and presents a diagnostic challenge for the physician. History, physical examination, chest radiographs, and electrocardiographic analysis are important in making the correct diagnosis. Diagnosis of ventricular tachycardia is supported by history of prior myocardial infarction or congestive ...

Narrow QRS Complex Tachycardias

Mayo Clinic Proceedings, 1995
Regular narrow QRS complex tachycardias are a common problem encountered by general internists or family practitioners. Although such tachycardias often occur in patients with a normal heart and seldom represent life-threatening conditions, they may cause bothersome symptoms.
