Heart Conduction Systemنظام التوصيل الكهربى بالقلب
The sinus node, displaying properties of
automaticity, spontaneously depolarizes,
sending a depolarization wave over the
atrium, depolarizing the atrioventricular(AV) node, propagating over the His-
Purkinje system, and depolarizing the
ventricle in systematic fashion.

Normal Sinus Rhythmالنبض الطبيعى
The normal
rhythm of the
heart, so-called
normal sinus rhythm.

Abnormal Heart Rhythm – Arrhythmia
اضطراب نبض القلب
Abnormality is in the normal activation sequence of the myocardium, there are hundreds of different types of cardiac arrhythmias.
Such arrhythmia could be:
1. Sick sinus syndrome (SSS).
2. Sinus tachycardia.
3. Premature atrial contractions (PACs)
4. Premature ventricular contractions (PVCs).
5. Atrial fibrillation.
6. Paroxysmal atrial tachycardia (PAT).
7. Supraventricular tachycardia (SVT).

Prevalenceاألعراض
Cardiac arrhythmias common
symptoms are: Dizziness, palpitations, and loss of consciousness or syncope.
Complaints such as fluttering, shortness
of breath, chest discomfort, and
forceful or painful extra beats are
commonly reported with various
arrhythmias.

Electrocardiograph ECG or EKGرسم القلب–التخطيط الكهربى للقلب
It is an noninvasive transthoracic interpretation of the electrical activity of the heart over a period of time, as detected by electrodes attached to the surface of the skin and recorded by a device external to the body.
An ECG is used to measure the rate and regularity of heartbeats, as well as the size and position of the chambers.
Most ECGs are performed for diagnostic or research purposes on human hearts.

ECG Leads & electrodes placementكابالت رسم القلب و توصيلها
Leads refer to the electrical cable attaching the electrodes to the ECG
recorder, 10 of these electrodes are standard in a "12-lead" ECG.

Holter ECGساعة24رسم القلب
Ambulatory electrocardiography device for continuously monitoring various electrical activity of the cardiovascular system for at least 24 hours.
Its extended recording period for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period of time.
It records electrical signals from the heart via a series of electrodes attached to the chest.
Electrodes are placed over bones to minimize artifacts from muscular activity.
These electrodes are connected to the Holter Device which will be attached to the patient's belt or hung around the neck.

Stress Test ECGرسم القلب بالمجهود
It is a test used to measure the heart's ability to respond to external
stress in a controlled clinical environment.
The stress response is induced by exercise or drug stimulation.
Cardiac stress tests compare the coronary circulation while the
patient is at rest with the same patient's circulation observed during
maximum physical exertion, showing any abnormal blood flow to
the heart's muscle tissue.
This test can be used to diagnose ischemic heart disease, and for
patient prognosis after a heart attack (myocardial infarction).
