conclusions switching ams off may increase biventricular pacing in some patients. case presentation in this case series, we present a combination of far field sensing and automatic mode switching (ams) in six patients. it is found that this combination causes ventricular sensing (vs) episodes with wide qrs and no synchronization. we turn off the ams and alleviate the problem. introduction cardi...

metastatic tumors to the heart unlike primary cardiac tumors are not rare. despite its frequency, cardiac metastasis is commonly detected only during autopsy as the symptoms of disseminated metastasis prevail over symptoms caused by cardiac metastasis and hence is overlooked most of the time. tumors more commonly found metastasizing to the heart are malignancies of lung, breast, esophagus, lymp...

effects of doxycycline on cx43 distribution and cardiac arrhythmia susceptibility of rats after myocardial infarction abstract: this study aimed to observe the effects of doxycycline (dox) on gap junction remodeling after mi and the susceptibility of rats to cardiac arrhythmia. the proximal left anterior descending coronary artery of rats was ligated to establish a myocardial infarction animal ...

objective: cardiopulmonary resuscitation (cpr) has been known in its present form since 1960. different studies have reported variable outcomes among different countries. therefore, the purpose of this study was to assess the rate of cpr success and the survival rate in managing cardiac arrest among patients in an educational medical center. methods: this cross-sectional study was performed at ...

Cardiac disorders remain one of the most important causes of death in the world. Oxidative stress has been suggested as one of the molecular mechanisms involved in drug-induced cardiac toxicity. Recently, several natural products have been utilized in different studies with the aim to protect the progression of oxidative stress-induced cardiac disorders. There is a large body of evidence that a...

Objective: Cardiac tamponade is a life-threatening clinical entity that requires an emergency treatment. Cardiac tamponade can be caused both by benign and malignant diseases. A variety of methods have been described for the treatment of these cases from needle-guided pericardiocentesis, balloon-based techniques to surgical pericardiotomy. The Authors report their experience in...

Abstract Introduction: Occurrence of cardiac arrhythmias and myocardial infarction are two main deleterious events that are caused by ischemia-reperfusion (IR) injury in the heart. Cardiac preconditioning represents the most potent method of rescuing heart tissue from undergoing irreversible ischemic damage. The aim of the present study was to evaluate oxytocin (OT) cardioprotective effect...
