Sick sinus syndrome of functional nature in children
In a study of 2239 patients the diagnosis of sick sinus syndrome was made in 120 children aged from 7 to 17 years of both sexes. According to the results of the cardiorespiratory synchronism test and to clinical methods that exclude organic heart disease,

Soft Syndrome Decoding of Quantum LDPC Codes for Joint Correction of Data and Syndrome Errors [PDF]
Quantum errors are primarily detected and corrected using the measurement of syndrome information which itself is an unreliable step in practical error correction implementations. Typically, such faulty or noisy syndrome measurements are modeled as a binary measurement outcome flipped with some probability.

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

Function and dysfunction of human sinoatrial node [PDF]
Sinoatrial node (SAN) automaticity is jointly regulated by a voltage (cyclic activation and deactivation of membrane ion channels) and Ca(2+) clocks (rhythmic spontaneous sarcoplasmic reticulum Ca(2+) release).

The Role of the Calcium and the Voltage Clocks in Sinoatrial Node Dysfunction [PDF]
Recent evidence indicates that the voltage clock (cyclic activation and deactivation of membrane ion channels) and Ca2+ clocks (rhythmic spontaneous sarcoplasmic reticulum Ca2+ release) jointly regulate sinoatrial node (SAN) automaticity.
