The QRS complex of the electrocardiogram in myocardial infarction with remarks on methods of recording. II

Abstract

Per medio del methodo del analyse del via del unda de accession, disveloppate in 1943 per Gardberg e Ashman, le autores ha analysate le alterationes electrocardiographic del complexo QRS post infarcimento myocardial in areas posterior, lateral, septal, anterior, e combinatemente ventricular. Le effectos del varie positiones electrocardiographic del corde super le resultante alterationes del complexo QRS post infarcimento myocardial es presentate graphicamente. Electrocardiogrammas illustrative es includite. Omne le patientes del presente serie esseva electrocardiographate ante le infarcimento myocardial. Assi un comparation de electiocardiogrammas pre- e post-infarcimental es possibile. Le remanente parte del reporto consiste de remarcas in re (1) methodos de registration electrocardiographic (includente varie systemas empleate in vectocardiographia spatial), (2) le importantia de prender in consideration le effectos de eccentricitate, (3) le potential del terminal commun, e (4) le inadequatia del uso de representation dipolic in certe situationes. Nos conclude que al tempore presente il non existe un methodo satisfacente pro le correction de errores de eccentricitate.
