Septal myocardial infarction refers to seeing Q waves in leads V1 and V2. early and late transition), pulmonaryДisease (emphysema, cor pulmonale, acute pulmonary embolism, and chest lead misplacement.(5) Septal Myocardial Infarction Pseudo Q waves can be seen with left bundle branch block, left ventricular hypertrophy, right ventricular hypertrophy, left anterior fascicular block, preexcitation, Wolff Parkinson White Syndrome, abnormal rotation of the heart (e.g. hypertrophic cardiomyopathy, infiltrative myocardial diseases such as amyloid) and cardiac tumors. Pathological Q waves are found with myocardial infarctions and cardiomyopathies (e.g. Q waves are considered insignificant if they are <0.04 seconds (<1 little box) wide and < 1/4 the amplitude of the R wave. (3,4) Q waves are abnormal in leads V1-V3.

Small Q waves, representing normal initial depolarization of the intraventricular septum, are normal and commonly seen in the inferior and anterolateral leads (leads 3, aVF, aVL, 1, V5 and V6).

Learn about these common ECG findings, and how to read ECGs with Executive Electrocardiogram Education () (2) Rarely this pattern is seen in atrial septal defects or pulmonary disease with increased right-sided heart pressures. (2) This pattern is not a precursor of a right bundle branch block or any other significant conduction abnormality. The R wave or R prime is not greater amplitude than the S wave. It may also be called an incomplete right bundle branch block and is described a QRS complex that is < 120 msec with a small R wave, followed by a deeper S wave, and another small R wave seen in V1 and/or V2.

(1) RSRвЂ™ in V1 or V2ДЄn rSRвЂ™ pattern V1 or V2 can be a normal finding or variant in a younger person or athlete.

Patients with nonspecific intraventricular conduction delays are at almost twice as great a risk of all-cause death and cardiovascular death, as compared with patients without NS IVCDs. Causes include large myocardial infarctions, myocardial fibrosis, amyloidosis, cardiomyopathies or ventricular hypertrophy. Nonspecific Intraventricular Conduction Delay (NS IVCD)ДЄ nonspecific intraventricular conduction delay (IVCD) is a slowing of conduction through the myocardium, that does not meet the criteria of a right or left bundle branch block. You look at an electrocardiogram (ECG) and it says вЂњ rSR prime in lead V1 or V2вЂќ or вЂњborderline left axis deviation.вЂќ What does that mean and what do you do? Here, I review multiple common, but puzzling ECG changes and explain what they mean and what can be done about them.
