    Electrophysiology of Normal Cardiac Rhythm

    The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase of...

    Electrocardiogram

    An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
    Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and the T...

    Correlation between ECG and Cardiac Cycle

    The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the cardiac cycle.
    A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...

    Electrocardiogram Fundamentals

    Introduction
    An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
    Definition
    An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
    Parts of an ECG
    An ECG utilizes electrodes on the skin to...

    ECG Interpretation of Rhythms

    An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
    Components of the Electrocardiogram
    The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
    ECG waveforms are divided by vertical and horizontal lines at standard intervals.
    The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
