... terminal force in electrocardiogram-lead V1 (PTFV1) was the only significantly abnormal P-wave index (adjusted hazard ratio: 2.56; 95% CI: 1.72–3.80). Therefore, we incorporated the PTFV1 with the CHA₂DS₂-VASc score to generate a P-combined score. For a 5-year IS risk, the P-combined...

... using Glasgow algorithm. P-wave duration, P-wave area, P-wave frontal axis, and prevalence of abnormal P terminal force in lead V₁ (aPTF-V₁) were assessed and compared at ARVC diagnosis, 10 years before and up to 15 years after diagnosis. Prior to ARVC diagnosis, none of the P...

... in SHR cells; however, its maximal specific conductance was significantly lower in LOS than in CTR rats (28.6±3.6 vs. 54.2±8.0 pS/pF, n=55, P<0.001). Voltage of half-maximal activation (V_1/2) of both I_to and I_f was unchanged...

... (I_f) was recorded in the majority of tested cells (n=51). The midpoint of the activation curve (V_1/2) was −78±2 mV (n=32), and specific current conductance of fully activated I_f (g_f,max) was 60±11 pS/pF. Reversal potential...

... for SHR and WKY respectively) [18, 28] . A Boltzmann model based on the partition theorem according to the general equation: was fitted to the activation data, where V (mV) is the test membrane potential, V_1/2 (mV) is the fitted potential for half-maximal activation...

...: a normal ECG is not a guarantee of cardiovascular health, nor is a pathological ECG an unequivocal sign of heart disease. This must always be remembered when interpreting an ECG. ECG artefacts automatic interpretation prominent r' in V1 normal ECG in inherited heart disease Q waves in asymptomatic...

...European Society of Cardiology T wave inversion in inferior and lateral leads of a 12-lead electrocardiogram (ECG) warrants further investigation for cardiomyopathies, ischaemic heart disease, and pericarditis. T wave inversion in the right precordial leads V1 to V3, namely V1 and V2...
