SpletBackground: In the absence of other electrocardiographic (ECG) abnormalities, QS deflections simultaneously in both of the leads V1-V2 may have multiple possible causes. Despite much information in the literature indicating that this is an unlikely pattern for pure septal infarction, such an ECG diagnosis is frequently given. SpletHISTORICAL REVIEW Burstein and Ellenbogen 1 found nine cases of the two types of pattern in a series of 15,000 electrocardiograms. In eight of their cases coronary occlusion had occurred, and in six pulmonary disease had been or was present.

"SpletAbstract. Tall lead V1 (tall RV1), defined as an R/S ratio equal to or greater than 1, is not an infrequent occurrence in emergency department patients. This electrocardiographic finding exists as a normal variant in only 1% of patients. Physicians should therefore be familiar with the differential diagnosis for this important QRS configuration.

Lead V1 records the opposite, and therefore displays a large negative wave called S-wave. The fourth vector: basal parts of the ventricles The final vector stems from activation of the basal parts of the ventricles. The vector is directed backwards and upwards. It heads away from V5 which records a negative wave … Prikaži več Naming of the waves in the QRS complex is easy but frequently misunderstood. The following rules apply when naming the waves: 1. A … Prikaži več The QRS complex can be classified as net positive or net negative, referring to its net direction. The QRS complex is net positive if the sum of the positive areas (above baseline) exceeds … Prikaži več Prolongation of QRS duration implies that ventricular depolarization is slower than normal. The QRS duration is generally <0,10 seconds but must be <0,12 seconds. If QRS duration is ≥ … Prikaži več Depolarization of the ventricles generate three large vectors, which explains why the QRS complex is composed of three waves. It is fundamental to understand the genesis of these … Prikaži več SpletAdditionally, the R/S ratio, which is the amplitude of the R-wave divided by the amplitude of the S-wave, can be calculated. At birth, the R/S ratio in lead V1 is greater than 1 (which simply means that the R-wave is greater than the S-wave). The R/S ratio in V1 should be >1 until the age of 3 years.
