t-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. this usually happens when the monitoring lead displays a tall t wave, which is also sharp. r wave sensing algorithms of the devices do not sense t wave because the slow rate of the t wave is much less than that of the r wave. but the slow rate of t waves may change with time and also beca...

conclusions ia fluid resuscitation is superior to iv resuscitation in hemorrhagic shock induced cardiac arrest. results while iv rl infusion failed to restore chest motion in mice (n = 5), ia rl infusion restored chest motion in all mice examined (n = 6) (p = 0.0067). in three mice, iv rl infusion after cardiac arrest showed no effect on cc. after failure of venous infusion, ia rl infusion was ...

right ventricular failure due to right coronary artery disease, right ventricular hypertrophy, stunning, abnormal septal motion, myocardial infarction, or non-homogeneous distribution of cardioplegia is an uncommon but serious complication of open heart surgery. we report a patient with severe right ventricular hypertrophy secondary to severe mitral valve stenosis and another patient with detac...

granulocytic sarcomas (chloromas) are rare extramedullary tumors consisting of primitive granulocytic cells. we report here on a case of a 23-year-old man who presented with a generalized swelling. he is known case of acute myelomonocytic leukemia. granulocytic sarcomas are rare, destructive, extramedullary tumor masses that consist of immature granulocytic cells. in this unusual patient's case...

the prospect of surgery can be frightening and more extensive surgery is included more anxious . knowledge of how to surgery reduces anxiety. hence,our goals are as follows :   what conditions can cause heart surgery? the majority of adults who should be considered for cardiac surgery , suffer from the disease of the heart valves or coronary artery disease or both.also, a few of them have conge...

myxoid is a common type of liposarcoma. cardiac metastasis of sarcoma is a rare diagnosis. transthoracic echocardiography is a useful tool for beginning the diagnosis. curative resection of metastasis and then combination systemic chemotherapy for advanced disease is recommended. we report a 50 year old woman who presented with a cardiac metastasis of high grade round cell liposarcoma to right ...
