mobitz was born on may 31, 1889 in st. petersburg, russia. he attended the local high school in meiningen (saxony, germany) from which he graduated in 1908. he then studied medicine at the universities of freiburg and munich, where he earned his doctorate in 1914 (“contributions to basedow disease”). he then worked at the surgical hospitals in berlin and halle as well as in internal medicine at the university hospitals of munich and freiburg. in munich, mobitz was promoted to the position of a senior lecturer thanks to his research on heart block. in 1928, after a 4-year tenure, he accepted a post in freiburg as associate professor and chief of staff of the clinic of internal medicine. in 1943, he became director of the medical hospital in magdeburg-sudenburg municipal hospital until the occupation by the soviet army in 1945. mobitz’s work was devoted to internal medicine and he was especially interested in cardiology. from 1924 to 1928, he published his famous key papers on av dissociation and heart block. in 1924, mobitz differentiated two types of second degree av block with the aid of the electrocardiogram and characterized their prognostic significance. with type i (mobitz type i), the pr interval increases gradually until there is a breakdown of av conduction. this form is identical to the previously described type of second-degree av block by wenckebach at the end of the nineteenth century. with type ii block (mobitz type ii), all conducted beats show a constant, typically normal pr interval, and conduction to the ventricles occurs at regular intervals. this form is identical to the type of av block described by hay in 1906 without the benefit of electrocardiography. mobitz included 2 : 1, 3 : 1 av block in his type ii classification, and indicated the serious nature of type ii block and its propensity to adams-stokes attacks.

the human heart is a four-chambered organ responsible for the distribution of blood throughout the body. while every physiological effort is made to ensure that such a vital organ can operate continuously without error, sometimes a pathological situation arises and the function of the heart is compromised. one such pathology arises when the electrical signal propagated throughout the heart (responsible for the heart's highly organized contractions) is hindered, resulting in a degradation of said conduction. this is referred to as a bundle branch block and is seen clinically as rate-dependent bundle branch block, right bundle branch block or left bundle branch block, in varying severity (first degree av block, second degree av block and third degree av block)
tachycardia-dependent bundle branch block
