“…The authors found an incidence of type 1, 2, and 3 Type 2 BrP on 0.8, 2, and 7.5%, respectively (Hunuk et al, 2013). In a population of 491 collegiate athletes a type 2 or 3 Type 2 BrP was seen in 58 (11.8%), and no definitive type 1 was observed (Chung et al, 2014). The much higher incidence of a type 2 or 3 Brugada ECG pattern mostly type 3 in our PVC patients, and its absence in the control group, raises the hypothesis that the two may be associated.…”

Idiopathic Premature Ventricular Contractions From the Outflow Tract Display an Underlying Substrate That Can Be Unmasked by a Type 2 Brugada Electrocardiographic Pattern at High Right Precordial Leads

Background: Patients with premature ventricular contractions (PVCs) from the right ventricular outflow tract (RVOT) and apparently normal hearts, can have ST elevation similar to type 2 or type 3 Brugada pattern in the electrocardiographic (ECG) performed at a higher position. Cardiac magnetic resonance (CMR), has shown conflicting data regarding existence of structural abnormalities in patients with idiopathic PVCs from the RVOT. Objective: Our aim was to evaluate the prevalence of low voltage areas (LVAs) in the RVOT of patients with PVCS from the outflow tract, and in a control group. Secondly, assess for the presence of a non-invasive ECG marker. Methods: A 56 consecutive patients, 45 with frequent PVCs (>10000/24 h) LBBB, vertical axis, negative in aVL and 11 subjects without PVCs. Arrhythmogenic right ventricular cardiomyopathy was ruled out in all patients. An ECG was performed with V1-V2 at the level of the second intercostal space and the presence of ST-segment elevation with a Type 2 or 3 Brugada pattern (Type 2 BrP) was assessed. Bipolar voltage map of the RVOT was performed in sinus rhythm (0.5-1.5 mV color display). Areas with electrograms <1.5 mV represented the LVA. The area adjacent to the pulmonary valve usually displays voltage between 0.5 and 1.5 mV and is classified as transitionalvoltage zone. Presence of LVAs outside this transitional-voltage zone were estimated. We compared two groups with and without ST-segment elevation and tested for the association between ECG pattern and LVAs.

“…Two electrode positions (V1 and V2) were selected in the experiment and the individual person might show different ECGs. After comparing ECG signals in three states, all of the acquired signals are acceptable because all the R-peaks were detected and the obtained ECG signals can be used to calculate the heart rate [ 38 , 39 ]. The ECG signals acquired from the running state are better than the signals acquired from static state and jogging state.…”

Smart garments, which can capture electrocardiogram signals at any time or location, can alert others to the risk of heart attacks and prevent sudden cardiac death when people are sleeping, walking, or running. Novel wearable electrodes for smart garments based on conductive chitosan fabrics were fabricated by electroless plating of silver nanoparticles onto the surfaces of the fibers. The electrical resistance, which is related to the silver content of the composite fabrics, can be as low as 0.0332 ± 0.0041 Ω/sq due to the strong reactivity between amine groups and silver ions. After washing these fabrics eight times, the electrical resistance remained below 1 Ω/sq. The conductive chitosan fabrics were applied to smart garments as wearable electrodes to capture electrocardiogram signals of the human body in static state, jogging state, and running state, which showed good data acquisition ability and sensitivity.

“…The findings in the relatively small control groups studied here argue against this conclusion, but a recent survey reported the type 2 to 3 ECG pattern in 11.8% of male athletes and 9.9% of population controls, when V1 and V2 were recorded using the second intercostal space. 16 Another recent study highlighted the frequency (≈2%) with which the type 1 Brugada ECG pattern was seen in febrile patients in an emergency room setting, 17 again suggesting that the asymptomatic syndrome is commoner than previously appreciated.…”
