…the CTI has been definitively ruled out. Typical flutter is closely related to atrial fibrillation (AF) in clinical practice. Both arrhythmias are associated with similar…

…Typical atrial flutter. The atrial rate (i.e the rate measured between flutter waves) typically ranges between 250 and 350 beats per minute (which is…

…and atrial enlargement. Below follows a discussion on the principles and differences of dilatation and hypertrophy, as well as typical ECG changes seen in atrial…

…Typical premature atrial contraction. Figure 2. Atrial premature beat with retrograde P wave. The QRS complex appears if the atrial impulse is conducted to the…

…and right atria causes typical P wave changes in lead II and lead V1 (Figure 1, second and third panel). P pulmonale: right atrial enlargement…

…may become markedly depressed. Right sided filling pressures—including central venous, right atrial, and right ventricular end diastolic pressures—are elevated, whereas left ventricular filling…

…will be enhanced. Enlargement of the left and right atria causes typical P wave changes in lead II and lead V1 ( Figure 3 ). Enlargement of…
