Why is your heart more complex than your circulatory
When there is no electrical activity in the heart (asystole), the AED won't start the heart as drugs are required to start the heart. The AED will only re-set the heart from abnormal electrical activity (such as V-Tach or V-Fib).
The brain does not send "electrical pulses" to the heart. Electrical impulses are actually generated within the heart itself (in the SA node), which travel through several intricate pathways from the atria down to the ventricles.
The His-Purkinje system is the part of the heart's electrical system that follows the outer walls of the ventricle.

The P waves represent the electrical activity that causes the atria to contract in the heart. They occur before the QRS complex on an electrocardiogram (EKG) and signify the depolarization of the atria.
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
T waves on an ECG represent the repolarization of the ventricles of the heart, indicating the relaxation phase of the heart's electrical activity.
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction
The Event Monitors are medical devices that record the heart's electrical activity and record the heartbeats only when symptoms of the heart problem occur.
ECG waves represent the electrical activity of the heart, showing how it beats and functions. They can help diagnose heart conditions and monitor cardiac health.
T waves are a part of the electrical activity in the heart that represent the repolarization of the ventricles. They help to reset the heart's electrical system after each heartbeat, allowing the heart to relax and prepare for the next contraction. This contributes to the overall function of the heart by ensuring that the heart beats in a coordinated and efficient manner.
There isn't a red heart event for any of the girls. There isn't a green heart event either. There is only a black heart event, a purple heart event, a blue heart event, and a yellow heart event.
The R wave in an electrocardiogram (ECG) represents the depolarization of the ventricles in the heart. It is a measure of the electrical activity during the contraction phase of the heart's pumping cycle.
The QRS complex corresponds to the depolarization of the ventricles in the heart. It represents the spread of the electrical signal that initiates the contraction of the ventricles. This is a critical step in the cardiac cycle that leads to the pumping of blood out of the heart.
The event that stimulates the contraction of cardiac muscle is the electrical signal generated by the sinoatrial (SA) node in the heart, also known as the pacemaker of the heart. This signal causes the heart muscle cells to contract and pump blood throughout the body.
The ECG wave tracing represents the electrical activity of the heart as it beats. It shows the depolarization and repolarization of the heart muscle, which corresponds to specific events in the cardiac cycle. The different waves and intervals on the ECG tracing provide information about the heart's rhythm, rate, and potential abnormalities.
