In addition, this is what will be present with a 1 st Degree AV Heart Block:
What Are ECG Characteristics of First-Degree AV Block?
The definition of first-degree atrioventricular (AV) block is a PR interval of greater than 0.20 seconds on electrocardiography (ECG) without disruption of atrial to ventricular conduction (figure). The normal measurement of the PR interval is 0.12 seconds to 0.20 seconds.
Sinus Rhythm means you heart is beating at a steady consistent rate. A first degree AV block means that the electrical signal that starts in the Atria (upper chambers) of the heart and is relayed to the Ventricles (lower chambers) of the heart, is taking too long to get there. It's sometimes referred to on the EKG as a prolonged PR time.

Complete heart block is the most serious type of AV heart block. It happens when the electrical impulses that tell your heart when to beat don't pass between the top (atria) and bottom chambers (ventricles) of your heart. This can affect the flow of blood to your body and brain.
Atrioventricular (AV) block is an interruption or delay of electrical conduction from the atria to the ventricles due to conduction system abnormalities in the AV node or the His-Purkinje system. Conduction delay or block can be physiologic if the atrial rate is abnormally fast or pathologic at normal atrial rates.
I44. 2 - Atrioventricular block, complete. ICD-10-CM.
2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave is not followed by a QRS complex.
First-degree atrioventricular (AV) block is a condition of abnormally slow conduction through the AV node. It is defined by ECG changes that include a PR interval of greater than 0.20 without disruption of atrial to ventricular conduction. This condition is generally asymptomatic and discovered only on routine ECG.
High-grade AV block, also known as advanced heart block, is a form of third-degree heart block. This occurs when AV dissociation is present; however, intermittently some sinus node action potentials (P waves) are randomly conducted to the ventricles.
An electrocardiogram (ECG) is the main test used to diagnose heart block. It measures the electrical activity of your heart. An ECG can be carried out at rest or while you're exercising. Your doctor may ask you to wear a portable ECG monitor to get a reading over time.

Impaired impulse conduction from heart atria to heart ventricles. Av block can mean delayed or completely blocked impulse conduction.

The 2022 edition of ICD-10-CM I44.1 became effective on October 1, 2021.
A disorder characterized by a dysrhythmia with a progressively lengthening pr interval prior to the blocking of an atrial impulse. This is the result of intermittent failure of atrial electrical impulse conduction through the atrioventricular (av) node to the ventricles.
Atrioventricular (AV) block involves impairment of the conduction between the atria and ventricles of the heart. In ICD-10-CM the codes are categorized by degree:#N#First degree AV block (I44.0 Atrioventricular block, first degree) – All atrial impulses reach the ventricles, but the conduction is delayed within the AV node. Patients are generally asymptomatic and the first-degree AV block is usually an incidental finding on electrocardiography (ECG). People with newly diagnosed first-degree AV block may be well-conditioned athletes, or they may have a history of myocardial infarction or myocarditis. First-degree AV block also may represent the first sign of degenerative processes of the AV conduction system.#N#Second degree AV block (I44.1 Atrioventricular block, second degree) – Atrial impulses fail to conduct to the ventricles. Patients may be asymptomatic, but may experience pre-syncope or syncope and sensed irregular heartbeats. The latter usually is observed in more advanced conduction disturbances, such as Mobitz II second-degree AV block. A history of medications that affect atrioventricular node (AVN) function (e.g., digitalis, beta-blockers, and calcium channel blockers) may be contributory and should be obtained. Other terms for a second degree AV block are Wenckebach’s and Mobitz blocks.#N#Third degree AV block (I44.2 Atrioventricular block, complete) – No supraventricular impulses are conducted to the ventricles. Patients have symptoms of fatigue, dizziness, light-headedness, pre-syncope, or syncope. Syncopal episodes due to slow heart rates are called Morgagni-Adams-Stokes (MAS) episodes, in recognition of the pioneering work of these researchers on syncope. Patients with third-degree AV block may have associated symptoms of acute myocardial infarction either causing the block or related to reduced cardiac output from bradycardia in the setting of advanced atherosclerotic coronary artery disease.#N#Proper coding of AV block requires documentation of severity:
