Asks if a P-wave precedes the QRS complex. Note: This represents normal conduction from the atria to the ventricles. If the P-wave is absent, the impulse is being generated from elsewhere in the heart. Assess whether all the complexes look the same. Note: Normal conduction follows the …

An hour later, she began to feel warm, restless, and anxious. Her husband noticed she was looking pale and said he would take her to a nearby walk-in clinic. By the time they arrived, Martha said her left arm and shoulder were sore. Suspecting Martha was having a heart attack, her husband turned the car around and rushed her to the hospital.

• The intrinsic conduction system of the heart initiates depolarization impulses. • Action potentials spread throughout the heart, causing coordinated heart contraction. • An ECG wave tracing records the electrical activity of the heart. ** Now is a good time to go to quiz questions 3 and 4:

Rate normal or bradycardia P wave those present are normal QRS normal Conduction normal Rhythm basic rhythm is regular*. *In a type I SA block, the P-P interval shortens until one P wave is dropped. *In a type II SA block, the P-P intervals are an exact multiple of the sinus cycle, and are regular before and after the dropped P wave.

The heart is a dual pump that circulates blood around the body and through the lungs. Blood enters the atrial chambers of the heart at a low pressure and leaves the ventricles at a higher pressure. The high arterial pressure provides the energy to force blood through the circulatory system. ... Components of the human heart involved in conduction.

The SA ryhthm is the normal pacemaker of the heart, firing at about 60-100 beats per minute. A heart controlled by the SA node is said to be in normal sinus rhythm. The electrical impulse from the SA node spreads over the right and left atria and causes atrial contraction. The impulses are also conducted to the . atrioventicular (AV) node

A. Prolonged - time longer than normal, configuration of the QRS complex is normal 1. prolonged conduction in dilated or hypertrophied ventricles . 2. time usually 0.10 – 0.12 seconds. 3. increase in muscle mass increases the depolarization time

In first degree block, the PR interval on the ECG is prolonged beyond the normal 0.20 seconds. Second degree block results from abnormalities in conduction through the AV node with consequent failure of some of the impulses to reach the ventricles. There are two types:
