Electrical Conduction System of the Heart

The heart’s electrical activity originates in the sinoatrial (SA) node, acting as the heart’s natural pacemaker. This electrical impulse spreads through specialized pathways, initiating coordinated contractions of the atria and ventricles. The conduction system includes the atrioventricular (AV) node, bundle of His, bundle branches, and Purkinje fibers. Each component plays a critical role in ensuring a timely and coordinated heartbeat.

The precise timing of these electrical signals is captured on an EKG tracing.

Components of a Typical EKG Tracing

A standard EKG tracing displays waveforms, reflecting the electrical activity of the heart. These waveforms, including the P wave, QRS complex, and T wave, represent distinct phases of the cardiac cycle. The intervals and segments between these waveforms also hold crucial information. For example, the PR interval signifies the time taken for the electrical impulse to travel from the SA node to the ventricles.

Understanding the shape, size, and timing of these components is vital for interpreting the EKG.

Types of EKG Rhythms and Their Interpretations

Various EKG rhythms reflect different heart conditions. Sinus rhythm, the most common, indicates normal heart function. Other rhythms, such as atrial fibrillation, atrioventricular blocks, and ventricular tachycardia, signify potential cardiac issues. Accurate interpretation involves identifying the specific pattern and correlating it with potential underlying medical conditions.

Common Cardiac Abnormalities Reflected in EKGs

Several cardiac abnormalities can manifest on an EKG tracing. For instance, myocardial ischemia, a reduced blood supply to the heart muscle, might show ST-segment depression or T-wave inversion. Myocardial infarction, commonly known as a heart attack, often shows characteristic Q waves and ST-segment elevation. Hyperkalemia, elevated potassium levels, might display prolonged PR intervals and widened QRS complexes.

Each abnormality has a distinct pattern on the EKG, aiding in diagnosis and treatment.

Illustrative Examples of EKG Rhythms

Unlocking the secrets of the heart’s electrical activity is crucial for diagnosing various cardiac conditions. This section dives into recognizable EKG patterns, helping you interpret the rhythm and understand its implications. From the reassuringly regular sinus beat to the irregular flutter of atrial fibrillation, we’ll explore key characteristics of each rhythm.

Normal Sinus Rhythm

Normal Sinus Rhythm (NSR) is the heart’s healthy, regular electrical pattern. It’s characterized by consistent P waves preceding each QRS complex. The P waves are upright in leads II, III, and aVF, and are typically narrow and rounded. The QRS complexes are also consistently shaped and of normal duration. The intervals between each beat are generally uniform, reflecting a steady heart rate.

This regularity is a hallmark of a well-functioning heart.

Atrial Fibrillation

Atrial fibrillation (AFib) is characterized by chaotic, irregular electrical activity in the atria. This irregularity shows up on the EKG as a lack of discernible P waves. Instead, the baseline is erratic, with no consistent pattern. The QRS complexes, while still present, may vary in shape and timing. The irregular rhythm of AFib is a key indicator of the condition.

Different types of AFib might show slight variations in the irregularity. Some may have a more rapid ventricular response, while others may be slower.

Premature Ventricular Contraction (PVC)

A premature ventricular contraction (PVC) is an extra, premature heartbeat originating from the ventricles. The EKG will show an extra QRS complex that’s often wider and bizarrely shaped compared to the normal QRS complexes. The P wave is absent before this extra beat, as the impulse doesn’t originate in the sinus node. PVCs can occur sporadically or in bursts, depending on the underlying cause.

First-Degree Heart Block

First-degree heart block is a condition where the electrical impulse is delayed as it travels from the atria to the ventricles. This delay manifests on the EKG as a prolonged PR interval. The P wave is still present and precedes each QRS complex, but the time between the beginning of the P wave and the beginning of the QRS complex is longer than the typical duration.

This is a key indicator for this condition.

Third-Degree Heart Block

Third-degree heart block, also known as complete heart block, is a significant condition where the electrical impulses from the atria don’t reach the ventricles. The EKG shows a complete dissociation between the P waves and the QRS complexes. The P waves are regular, but the QRS complexes have no consistent relationship to the P waves. The ventricles are pacing themselves independently at a slower rate, which can be problematic.

Bundle Branch Block

A bundle branch block (BBB) occurs when there’s a delay or blockage in the electrical pathway through one of the bundle branches. The EKG demonstrates a widened and distorted QRS complex. The specific pattern of the widening depends on whether the right or left bundle branch is affected. Right bundle branch block (RBBB) typically exhibits a characteristic “bunny ear” appearance in the QRS complex, while left bundle branch block (LBBB) exhibits a wider and notched QRS complex.

The presence of a bundle branch block suggests a potential underlying structural issue in the heart’s electrical conduction system.
