Overview

There is no established system for the classification of [disease name].

OR

[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].

OR

[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].

OR

Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.

OR

If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].

OR

The staging of [malignancy name] is based on the [staging system].

OR

There is no established system for the staging of [malignancy name].

Classification

• Paroxysmal AV Block may be classified according to the cause into three types :

1. Intrinsic AV Block (I-AVB)
2. Extrinsic Vagal AV Block (EV- AVB)
3. Extrinsic Idiopathic AV Block (EI- AVB) "Syncope and paroxysmal atrioventricular block - Aste - 2017 - Journal of Arrhythmia - Wiley Online Library".

Paroxysmal AV Block classification based on cause

Intrinsic AV Block (I-AVB): Due to innate structural/ conduction defect

Extrinsic Vagal AV Block (EV- AVB): Due to vagal surge/reflex

Extrinsic Idiopathic AV Block (EI- AVB) : Due to innately low adenosine plasma levels

Tachycardia Dependent AV Block (TD- AVB)

Bradcardia/Pause Dependent AV Block (BD- AVB/PD-AVB)
