What happens immediately after the QRS wave of the cardiac cycle?
There are a number of things that may happen during the QRS wave. There will be ventricular depolarization and right after absolute refractory period for ventricles will occur.
The period during which the ventricles are repolarizing?
the asnwer is t wave
What happens during the S T interval?
The S-T interval represents the initial slow phase of ventricular repolarization. It is the time between completion of the QRS complex and beginning of the T-wave
What happens during the S-T interval?

What is occurring within the heart during each part of the EKG?
The P wave measures the atriums. The Q,R,S Complex measures ventricles. The T wave measures repolarization.
What are T wave abnormalities on anterolateral leads?
t-wave adnormalities can be related to ischemia in the anterolateral muscle of the heart or could be caused by other factors such as electrolyte abnormalities.
What three major waves of electrical signals appear on the ECGEKG?
* The first wave is called the P wave. It records the electrical activity of the atria (the heart's upper chambers). * The second and largest wave, the QRS wave, records the electrical activity of the ventricles (the heart's lower chambers). * The third wave is the T wave. It records the heart's return to the resting state.
What happens in the cardiac cycle after the p wave?
The T wave on an ECG reading is the last wave in the cycle, and it represents the repolarisation of the heart. This means that the ventricles have just contracted sending blood around the body, and the heart is now 'resetting' itself ready for the next cycle.
What does abnormal t-wave mean?
Abnormality can be due to abnormal heart rhythms or cardiac muscle defects.
The p wave on an ecg is described as a positive deflection that corresponds to what?
The P wave corresponds to the atrial contraction... the 'beat' of the upper chambers of the heart. The QRS complex correponds to the ventricular contractoins.. the 'beat' of the other two chambers. The T wave represents relaxation of the heart muscle.
When is a p wave lost in the T wave?
this occurs with a premature beat known as a PAC (premature atrial contraction) A t wave is ventricular repolarization (the ventricle getting ready to beat again. A premature atrial contraction may happen at this time but you can discern the actual p wave as it is hidden in the t wave. Pac's are normal, most people have them occasionally. They can increase with stress, caffeine, smoking. The other cause would be in an irregularly fast arrhythmia in with the heart is beating so fast that the p wave is coming very close to the t wave and hard to discern it
What does a segment of an ECG tracing indicate?
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
