Angiotensin-converting enzyme 2 (ACE2) is a monocarboxypeptidase that metabolizes several peptides, including the degradation of angiotensin (Ang) II, a peptide with vasoconstrictive/proliferative effects, to generate Ang 1-7, which exerts vasodilatory/antiproliferative actions by acting through its receptor Mas. ACE2 is a multifunctional enzyme, and its actions on other vasoactive peptides, including ...

The mechanisms of sinoatrial node (SAN) dysfunction in heart failure (HF) remain unclear. We hypothesized that impaired rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release (Ca(2+) clock) plays an important role in SAN dysfunction in HF. HF was induced in canine hearts by rapid ventricular pacing. The location of pacemaking sites was ...

In the presented case, a screw-in pacemaker lead migrated through the right ventricle, pericardium, left hemidiaphragm, and the left liver lobe into the epigastric region. The rarity of the case is based upon the multiorgan perforation without development of relevant pericardial effusion or intra-abdominal bleeding. Lead extraction was performed uneventfully.

AIMS: In the normal heart, myocardial contractility is augmented at elevated heart rates. This effect is known as force-frequency relationship (FFR). The FFR is altered in failing hearts and may be used to detect myocardial function impairment. Force-frequency relationship measurements usually require invasive techniques and have therefore rarely been used ...

The R-on-T phenomenon is a well-known entity that predisposes to dangerous arrhythmias. Typically, a premature ventricular complex occurring at the critical time during the T wave of the preceding beat precipitates ventricular tachycardia and fibrillation. This phenomenon can occur not only in asynchronous ventricular pacemakers, but also in synchronous pacemakers, ...

Patients undergoing tricuspid valve replacement who already have a transvenous pacemaker system in the right ventricle are often recommended to have the ventricular lead removed and an epicardial system implanted. However, as a rule, the reliability of endocardial transvenous pacemaker leads has been superior to epicardial systems. Therefore, if the ...
