例如,束支阻滞在每个QRS波前有相同的P波,PR间期介于0.12和0.20秒之间,QRS为0.12秒或更短,并具有独特特征,例如V1中ST段抬高或呈RSR’型。 心脏骤停 尽管评估心电图预测心脏骤停价值的研究有限,但既往研究已经提供了一些见解。例如,...

55、Acute anterior MI and the right bundle branch block (RBBB) patternThe wide QRS complexes with an rSR wave in lead V1 and a qRS pattern in lead V5 indicate the presence of RBBB. A pattern of acute anterior wall infarction is indicated by the Q waves and ST elevations in leads I an...
High precordial leadECGSudden DeathArrhythmiaAthletesDifferentiating true Brugada pattern from rSr' patterns in V1-V2 is difficult.rSr' pattern can be seen when ECG leads are placed in the 2nd intercostal space.We used high lead ECGs and three new criteria to differentiate potential Brugada from ...

(two) clinical significance: the ECG pattern of typical right ventricular hypertrophy shows that right ventricular hypertrophy is quite significant. Normal people sometimes appear R/S>1 or rsR wave in VI, so it is not necessary to diagnose right ventricular hypertrophy only according to one index,...
