Holter monitoring of myocardial ischemia

Regulation crown expansion, blood circulation, nutrition, cardiac and other treatment. 1.2 Methods: Beijing Instrument Software Technology Co., Ltd. U.S. high production EGCLAB Holter system. 1O a patient's body placed disposable medical electrodes, placed one chest lead ECG V with a V position, limb lead positions can be Ma, son-Likar limb lead systems approach to improve placement. Connect with the lead electrodes and the recorder can record 24d ', when the 12-lead ECG. And request a complete record of the daily activities of patients (active, resting, eating, medication,[link widoczny dla zalogowanych], emotional events, sleep, etc.) and time, detailed records of symptoms when symptoms start and end time and experience. Under the criteria for horizontal or oblique-type ST segment under the Mu ≥ 0.1mV (the J point in paragraph 60-80m8 and the midpoint of PQ monitoring points), for 1 minute, two at least once every 1 minute 11 ischemic attack . Determination of average heart rate, heart rate ischemic attack. 2 false positive results exclude interference. CPC detected in 64 cases of myocardial ischemic attack 610 times, 125 episodes per patient,[link widoczny dla zalogowanych], with an average of 9.5 times, ST segment depression ranges from 0.1-0.55mV, 8 patients with typical angina. With chest tightness, hold breath, which are not typical defects like l0 cases,[link widoczny dla zalogowanych], 46 cases without any symptoms. 64 patients were an average heart rate of 72 beats / min, myocardial ischemia, the average heart rate 94 beats / minute during the day and 64 cases of ischemic 480 times (80.6%), which occurs when the rate of 5 to 7 the highest,[link widoczny dla zalogowanych], up to 300 times (70 .1%), nighttime 130 (19.4%). To myocardial ischemia such as heart attack than the average heart rate when ≥ l0 times / divided into fast frequency dependence, 64 cases were in the fast frame rate by 3l cases (48.4%). Slow frequency dependence in 5 patients (7%). 3 Discussion It was found that Holter monitoring of silent myocardial ischemia is the most important means. However, the diagnosis of silent myocardial ischemia in coronary heart disease must be diagnosed with the premise. ST segment Holter monitoring recorded no abnormal changes in pain symptoms can be established Xun. Over the past 2O years of research have proven silent myocardial ischemia is usually more severe in the outer membrane of vascular obstruction. Proximal lesions, complicated plaques thrombosis or ulceration of the lesion of coronary artery lumen irregularity It1. Therefore, asymptomatic myocardial ischemia than those with symptoms worse prognosis. A higher incidence of sudden death. In patients with coronary heart disease have a 84% 68% ischemic ST-T changes are asymptomatic. The observations show. 64 patients with coronary heart disease in asymptomatic patients with ischemic ST segment changes in 46 patients (71.9%), with typical angina in only 8 cases (12.5%). Coronary heart disease events in patients with mild or early morning when the cause of angina, and live in other time as the load is not. Individual patients Jizou, climbing stairs, or smoking, drinking can also cause significant when throwing ST-T changes. And myocardial ischemia was observed mostly in the biological clock rhythm, the highest rate after the early morning wake up. And sudden changes in heart rate also Town to increase the number of episodes of myocardial ischemia. Continuous monitoring of the 12 lead ECG, the detection rate of myocardial ischemia. Diagnosis can also locate, especially with atypical symptoms of myocardial ischemia,[link widoczny dla zalogowanych], myocardial infarction or asymptomatic myocardial ischemia irreplaceable clinical value. ST-T changes associated with time synchronization of activities. Help determine the type of myocardial ischemia and its drug of choice. In addition. Also predicted the possibility of sudden cardiac death, easy to take early preventive measures.
