DOI: 10.1007/s10840-018-0318-2
Abstract: PurposeThe ultrarapid delayed rectifier current (IKur) carried by Kv1.5 channels, which are solely expressed in the atrium, is a potential target for safer treatment of paroxysmal atrial fibrillation (PAF). XEN-D0103 is a nanomolar ion channel… read more here.

Insights into sinus arrhythmia of the dog: Acetylcholine perfusion of canine right atrium results in beat-to-beat patterns that mimic sinus arrhythmia supporting exit block in the sinoatrial conduction pathways.

DOI: 10.1016/j.tvjl.2021.105651
Abstract: Sinus arrhythmia of the dog is unique because of the pronounced alternating beat-to-beat intervals. The clustering of these short (faster rates) and long (slower rates) intervals is not just influenced by autonomic input from breathing;… read more here.

Pulse transit time-estimated blood pressure: a comparison of beat-to-beat and intermittent measurement
Sign Up to like & getrecommendations! Published in 2022 at "Hypertension Research"
DOI: 10.1038/s41440-022-00899-z
Abstract: Pulse transit time (PTT), which refers to the travel time between two arterial sites within the same cardiac cycle, has been developed as a novel cuffless form of continuous blood pressure (BP) monitoring. The aim… read more here.

DOI: 10.1038/s41440-024-01595-w
Abstract: Increased blood pressure variability (BPV) was shown to be associated with cardiovascular morbidities and/or mortalities. There are various types of BPV depending on time intervals of BP measurements, ranging from beat-to-beat to visit-to-visit or year-to-year.… read more here.

DOI: 10.1093/ajh/hpac107
Abstract: BACKGROUND Emerging evidence has linked visit-to-visit, day-to-day and 24-hour ABPM blood pressure variability (BPV) with cognitive impairment. Few studies have, however, considered beat-to-beat BPV. This study, therefore, evaluated the relationship between beat-to-beat BPV and cognitive… read more here.
