Dysfunction of sinus node (DSN) is the syndrome, characterized by symptoms of tissue hypoperfusion and manifestations on the electrocardiogram and could potentially lead to sudden death. The various impact of different types of pacemakers on life quality

Are physiological oscillations physiological?
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Diabetes increases mortality after myocardial infarction by oxidizing CaMKII [PDF]
Diabetes increases oxidant stress and doubles the risk of dying after myocardial infarction, but the mechanisms underlying increased mortality are unknown.

A photoisomerizable muscarinic antagonist. Studies of binding and of conductance relaxations in frog heart [PDF]
These experiments employ the photoisomerizable compound, 3,3'-bis- [alpha-(trimethylammonium)methyl]azobenzene (Bis-Q), to study the response to muscarinic agents in frog myocardium. In homogenates from the heart, trans-Bis-Q blocks the binding of [3H]-N-

ABSTRACT We report a case of a 41‐year‐old man with recurrent nocturnal ventricular asystole secondary to advanced atrioventricular (AV) block, which was successfully treated with ganglionated plexus (GP) ablation based on the presumption of excessive vagal tone. This approach may offer a potential alternative for vagally mediated nocturnal AV block in

CAROTID ARTERY STENTING IN A PATIENT WITH SINUS BRADYCARDIA: CLINICAL CASE
Syndrome of hemodynamic depression is a frequent complication of the carotid artery endovascular intervention and, as a rule, is transient in nature. This article presents a clinical case of carotid artery stenting in a 63-year-old patient.

Adenylyl cyclase isoform 1 contributes to sinoatrial node automaticity via functional microdomains
Sinoatrial node (SAN) cells are the heart’s primary pacemaker. Their activity is tightly regulated by β-adrenergic receptor (β-AR) signaling. Adenylyl cyclase (AC) is a key enzyme in the β-AR pathway that catalyzes the production of cAMP.

The function of the sinoatrial node (SAN), the pacemaker of the heart, declines with age, resulting in increased incidence of sinoatrial node dysfunction (SND) in older adults.
