[1] [3] In general, the symptoms of the syndrome are a combination of decreased cardiac output, loss of atrial contribution to ventricular filling, loss of total peripheral resistance response, and nonphysiologic pressure waves. [2] [4] [5] Individuals with a low heart rate prior to pacemaker implantation are more at risk of developing ...
Twiddler's syndrome is a malfunction of a pacemaker due to manipulation of the device and the consequent dislodging of the leads from their intended location. As the leads move, they stop pacing the heart and can cause strange symptoms such as phrenic nerve stimulation resulting in abdominal pulsing or brachial plexus stimulation resulting in rhythmic arm twitching.

Lev's disease may present with various signs and symptoms; however, these may overlap with similar conditions such as atrioventricular (AV) blocks. Signs of Lev's disease may include syncope, shortness of breath, dizziness, heart failure, and sudden cardiac death. Signs may begin to appear as an adult. [2]
Transcutaneous pacing is accomplished by delivering pulses of electric current through the patient's chest, which stimulates the heart to contract. [ citation needed ] The most common indication for transcutaneous pacing is an abnormally slow heart rate .
In terms of how a “mini heart attack” is treated, Dr. Mehta says that, typically, a doctor will do an imaging test such as an electrocardiogram or cardiac MRI to confirm that what happened was ...
This condition can be detected on an electrocardiogram (ECG) as a brief period of irregular length with no electrical activity before either the sinoatrial node resumes normal pacing, or another pacemaker begins pacing. If a pacemaker other than the sinoatrial node is pacing the heart, this condition is known as an escape rhythm.
Symptoms of testicular cancer can include a bump on a testicle or a swollen testicle, according to the American Cancer Society. Often, signs do not develop until the cancer is more advanced, the ...
Ventricular pacemaker with 1:1 retrograde ventriculoatrial (V-A) conduction to the atria (arrows). VA conduction, also named Ventriculoatrial conduction and sometimes referred to as Retrograde conduction, is the conduction backward phenomena in the heart, where the conduction comes from the ventricles or from the AV node into and through the atria.
