Hypertension is an important modifi able cardiovascular risk factor. Left ventricular hypertrophy - the marker of hypertension, has emerged as an independent risk factor that can be detected by electrocardiography (ECG)and echocardiography (ECHO).
Correlation of electrocardiography and echocardiographically detected left ventricular hypertrophy in hypertensive patients.
Hundred patients with hypertension were studied for left ventricular hypertrophy by the help of electrocardiography and echocardiography. Left ventricular hypertrophy on ECG was assessed by the help of Sokolow-Lyon Voltage Criteria (SLV) and Romhilt - Estes Point Score (R/E).
Among 100 patients, 60 were males and 40 were females. Mean age for male was 54.82 + or - 12.10 years and 52.95 + or - 11.63 years for female. The mean systolic blood pressure for male was 150.47 + or - 20 mmHg and for female 148.60 + or - 16.95 mmHg; where as Diastolic blood pressure for male was 93.67 + or - 11.13 mmHg and for female it was 96.05 + or - 12.47 mmHg. Echocardiography detected left ventricular hypertrophy in 64% patients. Electrocardiography detected Left Ventricular Hypertrophy by R/E and SLV criteria 13% and 34% respectively.
In developing and under developed country ECG is a useful tool for detection of LVH where the facilities of echocardiography and trained echocardiographer are still not in a common man's reach.
高血压是一种重要的可改变的心血管危险因素。左心室肥厚——高血压的标志物，已成为一种可通过心电图（ECG）和超声心动图（ECHO）检测到的独立危险因素。
探讨高血压患者心电图与超声心动图检测左心室肥厚的相关性。
借助心电图和超声心动图对100例高血压患者进行左心室肥厚研究。通过Sokolow-Lyon电压标准（SLV）和Romhilt-Estes积分（R/E）评估心电图上的左心室肥厚。
100例患者中，男性60例，女性40例。男性平均年龄为54.82±12.10岁，女性为52.95±11.63岁。男性平均收缩压为150.47±20 mmHg，女性为148.60±16.95 mmHg；男性舒张压为93.67±11.13 mmHg，女性为96.05±12.47 mmHg。超声心动图检测出64%的患者有左心室肥厚。心电图通过R/E和SLV标准检测左心室肥厚的比例分别为13%和34%。
在发展中国家和欠发达国家，心电图是检测左心室肥厚的有用工具，因为超声心动图设备和训练有素的超声心动图医生尚未普及到普通人。
