İEW Be careful-files from the Internet can contain viruses. Unless you need to edit, it's safer to stay in Protecte The picture represent traces from leads I, II, and IlI l. Plot the MEA on the graph to the correct 30 degree slice 2. Which of the augmented leads (e.g. Av depolarization? How can you tell? would record the largest deflection for ventricular 3. If the recordings above were due to a ventricular hypertrophy, what is the most likely location of the hypertrophy? rds e here to search 13

Answer 1

2)Avr means the augmented Vector Right , the positive electrode is on the right shoulder. Avl means augmented vector left, the positive electrode is on the left shoulder. Avf means augmented Vector Foot the positive electrode is on the foot.

3) The location is the heart. The most common cause of ventricular hypertrophy is high blood pressure. Other causes include athletic hypertrophy, valve disease, hypertrophic cardiomyopathy abd congenital heart disease.

5)Electrical signals arising in the SA node stimulate the atria to contract. Then the signals travel to the atrioventricular node which is located in the interatrial septum. After the delay the electrical signal diverges and is conducted through the left and right bundles.
