Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body.

Comorbid Conditions

Factors Influencing Duration

The type of heart block, cause, treatment, response to treatment, underlying comorbid conditions, complications, and age of the patient may all affect length of disability.

Medical Codes

ICD-9-CM:
426 - Conduction Disorders
426.0 - Atrioventricular Block, Complete Third-degree
426.1 - Atrioventricular Block, Other and Unspecified
426.10 - Atrioventricular Block, Unspecified; Atrioventricular (AV) Block (Incomplete) (Partial)
426.11 - Atrioventricular Block, First Degree; Incomplete Atrioventricular Block, First Degree, Prolonged P-R Interval NOS
426.12 - Atrioventricular Block, Mobitz (Type) II, Second Degree; Incomplete Atrioventricular Block
426.13 - Atrioventricular Block, Other Second Degree
426.2 - Left Bundle Branch Hemiblock
426.3 - Left Bundle Branch Block, Other
426.4 - Right Bundle Branch Block
426.5 - Bundle Branch Block, Other and Unspecified
426.50 - Bundle Branch Block, Unspecified
426.51 - Right Bundle Branch Block and Left Posterior Fascicular Block
426.52 - Right Bundle Branch Block and Left Anterior Fascicular Block
426.53 - Bilateral Bundle Branch Block, Other; Right Bundle Branch with Left Bundle Branch Block (Incomplete) (Main Stem)
426.54 - Trifascicular Block
426.6 - Heart Block, Other; Intraventricular Block NOS, Diffuse, Myofibrillar; Sinoatrial Block; Sinoauricular Block
426.8 - Conduction Disorders, Other Specified
426.9 - Conduction Disorder, Unspecified; Heart Block NOS; Stokes-Adams Syndrome

Prognosis

Individuals with first-degree or Mobitz type I heart block can expect no adverse effects unless there is progression to more severe forms of the condition. Mobitz type II often progresses to third-degree AV block especially in individuals with MI. This condition can result in unpredictable incidences of syncope and the possibility of sudden cardiac death (SCD) if left untreated. After pacemaker implantation, however, most individuals show improvement within 1 month and can usually resume most tasks associated with daily living.
