It is a common arrhythmia and can cause a slow, normal, or fast heart rate. Conduction disorders, specifically heart block, can cause a disruption to the electrical signals that enable the heart ...

Because third-degree heart block can be intermittent, an ECG may not diagnose it. Heart rhythm monitoring can be done with a Holter monitor or a patch monitor. These devices help diagnose an ...

and heart block. Implantable cardioverter-defibrillators (ICDs) are devices implanted under the skin. They monitor heart ...

Less commonly, sinus arrhythmia may indicate an underlying medical problem, like heart disease or heart block. The heart's normal sinus rhythm is created by electrical signals that spread ...

Participants who walked faster were more likely to be men, live in less deprived areas, have healthier lifestyles and weigh ...

Note the irregular R-R intervals making 3rd degree heart block unlikely. The rhythm on this ECG needs to be distinguished from high grade AV block which is a form of 3rd degree AV block that can ...

Montpellier and Copenhagen have identified why some endurance athletes experience a heart rhythm disturbance called ‘heart block’. The University of Manchester-led study found that long-term exercise ...

The rhythm starts as normal sinus rhythm with a right bundle branch block, then a wide-complex tachycardia ... the 12-lead ECG tracing, although the heart rate during the tachycardia is almost ...

Arrhythmias affect the electrical system in the heart and cardiomyopathies affect the structure ... and a fraction of these letters make up the genes that encode the building blocks of each cell. A ...

A brisk walking pace, and the amount of time spent at this speed, may lower the risk of heart rhythm abnormalities, such as ...

An international team of scientists from Manchester, Montpellier and Copenhagen have identified why some endurance athletes experience a heart rhythm disturbance called “heart block”.

The method combines electrocardiographic imaging (ECGI) with digital twins of the heart, which helps to improve the accuracy with which the focus where these arrhythmias originate can be identified.
