Inappropriate sinus tachycardia presented during pregnancy (clinical case)

Acta Biomedica Scientifica
Inappropriate sinus tachycardia (IST) is a sinus tachycardia unexplained by visible physiological and secondary causes with a resting heart rate of more than 100 beats per minute. The true prevalence of IST is unknown.

Prospective blinded evaluation of a novel sensing methodology designed to reduce inappropriate shocks by the subcutaneous implantable cardioverter-defibrillator [PDF]

, 2018
Background: Most inappropriate shocks from the subcutaneous implantable cardioverter-defibrillator (S-ICD) are caused by cardiac oversensing. A novel sensing methodology, SMART Pass (SP; Boston Scientific Corporation, Natick, MA), aims to reduce cardiac ...

Function and dysfunction of human sinoatrial node [PDF]

, 2015
Sinoatrial node (SAN) automaticity is jointly regulated by a voltage (cyclic activation and deactivation of membrane ion channels) and Ca(2+) clocks (rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release).

Inappropriate sinus tachycardia — ailment or disease?

Kardiologia Polska, 2013
We present a case of a 36-year-old female patient with a long history of persistent palpitations, limited exercise tolerance, and pre-syncope. ECG recordings revealed long lasting episodes of inappropriate sinus tachycardia (IST). IST is characterised by persistent cardiac arrhythmias with sinus P waves in the ECG, and an exaggerated response to a ...

Automatic Mode Switching in Atrial Fibrillation [PDF]

, 2005
Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

Monomorphic Ventricular Arrhythmias in Athletes. [PDF]

, 2019
Ventricular arrhythmias are challenging to manage in athletes with concern for an elevated risk of sudden cardiac death (SCD) during sports competition. Monomorphic ventricular arrhythmias (MMVA), while often benign in athletes with a structurally normal

Werner Irnich: Pioneer in the Development of the Dual‐Chamber Pacemaker—An Obituary

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Fifty years ago, Werner Irnich presented the concept of an optimal pacemaker capable of responding appropriately to various cardiac arrhythmias and perceptual disturbances, and intended to be used in 85% of patients. With this concept, Irnich was far ahead of his time. His proposed circuitry for AV block and atrial fibrillation, as well as his
