A hypermagnesemic adult sheep during an experimental study showed gastraointestinal and respiratory changes along with cardiovascular alterations included of obvious bradycardia and heart block. In order to save the animal from fatal bradycardia, atropine sulfate was administrated instatntly at one dose 0.3 mg/kg. The animal was survived and rhythm returned to sinus rhythm from marked bradycard...

Cardiac rupture is rare but potentially life-threatening complication after chest trauma. We present the case of a 57-year-old male who developed cardiac arrest because of extensive pericardial tamponade after a falling injury. We decided to perform an exploratory sternotomy in the operating room (OR). The patient was transported to the OR on extracorporeal membrane oxygenation (ECMO) support. ...

We report a rare case of fatal cardiac tamponade attributed to coronary sinus thrombosis. An 83-year-old man was admitted to the hospital complaining of general fatigue. Laboratory examination revealed marked increase of atypical lymphoblastic cells in peripheral blood. CHOP therapy was started under the diagnosis of acute lymphoblastic leukemia. The patient died, however, of sudden cardiac arr...

We report a case of intraoperative severe bradycardia that resulted in asystole and cardiac arrest shortly after (<2 min) intravenous granisetron 1mg for postoperative nausea and vomiting prophylaxis, that occurred in a female patient who underwent an elective total thyroidectomy. After two cycles of cardiopulmonary resuscitation and defibrillation, spontaneous circulation and sinus rhythm retu...

Oxidative stress during cardiac arrest may inactivate myocardial enzymes and thereby exacerbate ischemic derangements of myocardial metabolism. This study examined the impact of cardiac arrest on left ventricular enzymes. Beagles were subjected to 5 min of cardiac arrest and 5 min of open-chest cardiac compressions (OCCC) before epicardial direct current countershocks were applied to restore si...

This report describes a patient with complex partial seizures arising from the right temporal lobe who developed symptomatic sinus arrest following the end of his seizure activity. A ventricular pacemaker was implanted and was documented to function appropriately, preventing development of bradycardia associated symptoms during subsequent seizures. Possibly relevant cerebral structures are brie...

The infiltration of dilute epinephrine solution has been used for many years to provide hemostasis. However, epinephrine has adverse cardiovascular effects, such as arrhythmia, pulmonary edema, and even cardiac arrest. We have experienced epinephrine-induced cardiovascular crisis, with severe hypertension, tachycardia, and cardiac arrest after subcutaneous infiltration of a 2% lidocaine and 1 :...

We present a case of a rare complication of transvenous right ventricular pacing by temporary pacing wire causing iatrogenic interventricular septal perforation and left ventricular pacing in a 69-year-old man who was referred for recurrent syncope with sinus arrest.

The role of cardiac nerves in the production of cardiac arrest during surgical anaesthesia on coronary ligated hypoxic heart has been studied. When atropinished coronary ligated dogs were exposed to hypoxia the terminal event was a cardiac asystole in 88% of the dogs. In propranolol treated dogs, or in dogs where sympathetic ganglia upto T6 were bilaterally removed earlier, coronary ligation an...

COVID-19 patients may experience with a wide range of cardiovascular complications during infection: obstructive and non-obstructive coronary artery disease-acute syndrome (myocardial infarction type 1 2), arterial or venous thromboembolic diseases, myocarditis, pericarditis, pericardial effusion, stress cardiomyopathy (Takotsubo syndrome), arrhythmias, acute heart failure, shock sudden cardiac...
