七十多年来,常规12导联心电图在诊断疾病上积累了丰富的经验,可满足一般临床诊断的需要。但常规心电图的导联太少,测定部位较局限,在诊断范围上有一定限制。为了提高阳性检出率,降低误诊率,有时尚需加做某些特殊的心电图导联。为此,本文将一些特殊的导联的连接及临床应用分述于后。 一、单极导联 背部导联(V_7、V_8、V_9导联)、右胸导联(V_3R——V_8R导联)、V′_1——V_5~′,及V,1——V,5导联对诊断心室肥大、 For more than 70 years, the routine 12-lead ECG has accumulated rich experience in diagnosing diseases and can meet the needs of general clinical diagnosis. However, the lead of conventional ECG is too small, the measurement site is more limited, there are some limitations in the diagnostic scope. In order to improve the positive detection rate and reduce the misdiagnosis rate, it is sometimes necessary to add some special ECG leads. To this end, this article will be some special lead connections and clinical applications are described later. First, the unipolar lead back lead (V_7, V_8, V_9 leads), right chest lead (V_3R - V_8R lead), V’_1 - V_5 ~ ’, and V, 1 - V, 5 Lead on the diagnosis of ventricular hypertrophy,
