Understanding Electrocardiography (ECG): Hartman’s Complete Guide For The Ekg Technician

Electrocardiography (ECG) is a non-invasive medical test that records the electrical activity of the heart. It is used to diagnose a wide range of cardiac conditions, including arrhythmias, heart attacks, and heart failure. ECGs are also used to monitor the heart during surgery and other medical procedures.

ECG recordings are made using electrodes that are placed on the skin. These electrodes detect the electrical impulses generated by the heart and transmit them to an ECG machine. The ECG machine then records the impulses on a strip of paper or a digital display.

The ECG waveform is a graphical representation of the electrical activity of the heart. It consists of a series of waves and deflections that correspond to the different phases of the cardiac cycle.

Types of ECG Leads

There are 12 standard ECG leads that are used to record the electrical activity of the heart from different angles. These leads are:

• Lead I: Measures the electrical activity between the left arm and right arm.
• Lead II: Measures the electrical activity between the right arm and left leg.
• Lead III: Measures the electrical activity between the left arm and left leg.
• Leads aVR, aVL, and aVF: Measure the electrical activity from the right arm, left arm, and left leg, respectively.
• Leads V1, V2, V3, V4, V5, and V6: Measure the electrical activity from different locations on the chest.

Anatomy and Physiology of the Heart

The heart is a muscular organ that pumps blood throughout the body. It is located in the center of the chest, behind the sternum. The heart is divided into four chambers: two atria and two ventricles. The atria are the upper chambers of the heart, and the ventricles are the lower chambers.

The heart’s electrical conduction system is responsible for generating the electrical impulses that cause the heart to contract. The electrical impulses originate in the sinoatrial node (SA node), which is located in the right atrium. The SA node is the natural pacemaker of the heart.

The electrical impulses from the SA node travel through the atria to the atrioventricular node (AV node), which is located between the atria and ventricles. The AV node delays the electrical impulses slightly, which allows the atria to fill with blood before the ventricles contract.

The electrical impulses from the AV node travel through the bundle of His, which is a group of fibers that connect the AV node to the ventricles. The bundle of His divides into the left and right bundle branches, which carry the electrical impulses to the left and right ventricles.

The electrical impulses cause the ventricles to contract, which pumps blood out of the heart.

Normal ECG Interpretation

A normal ECG waveform consists of a series of waves and deflections that correspond to the different phases of the cardiac cycle. The normal ECG waveform is characterized by the following:

• P wave: The P wave represents the electrical activity of the atria.
• QRS complex: The QRS complex represents the electrical activity of the ventricles.
• T wave: The T wave represents the electrical activity of the ventricles repolarizing.
• U wave: The U wave is a small deflection that sometimes follows the T wave.

Arrhythmia Recognition and Interpretation

Arrhythmias are abnormal heart rhythms. They can be caused by a variety of factors, including heart disease, electrolyte imbalances, and medications. Arrhythmias can be classified into two main types: supraventricular arrhythmias and ventricular arrhythmias.

Supraventricular arrhythmias originate in the atria or AV node. They are typically characterized by a rapid heart rate and regular rhythm. Ventricular arrhythmias originate in the ventricles. They are typically characterized by a slow heart rate and irregular rhythm.

Common Arrhythmias, Hartman’s complete guide for the ekg technician

• Sinus tachycardia: A sinus tachycardia is a heart rate that is greater than 100 beats per minute. It is usually caused by exercise, stress, or fever.
• Sinus bradycardia: A sinus bradycardia is a heart rate that is less than 60 beats per minute. It is usually caused by medications, hypothyroidism, or athletic training.
• Atrial fibrillation: Atrial fibrillation is the most common type of arrhythmia. It is characterized by a rapid and irregular heart rate.
• Ventricular tachycardia: Ventricular tachycardia is a heart rate that is greater than 100 beats per minute and originates in the ventricles.
• Ventricular fibrillation: Ventricular fibrillation is a heart rate that is greater than 300 beats per minute and originates in the ventricles. It is a medical emergency.
