“…PR intervals start at the onset of the P wave and end at the start of the QRS complex. A PR interval of less than 120 ms is considered as the short PR interval, 49 and it may belong to normal electrocardiogram or a combination of different electrocardiographic abnormalities. 50 It is evident that both KAUST single-lead ECG (PR interval = 110) and commercial single-lead ECG detected a short PR interval (PR interval = 98).…”

Recent advances in electrocardiogram (ECG) diagnosis and monitoring have triggered a demand for smart and wearable ECG electrodes and readout systems. Here, we report the development of a fully screen-printed gentle-to-skin wet ECG electrode integrated with a scaled-down printed circuit board (PCB) packaged inside a 3D-printed antenna-on-package (AoP). All three components of the wet ECG electrode (i.e., silver nanowire-based conductive part, electrode gel, and adhesive gel) are screen-printed on a flexible plastic substrate and only require 265 times less metal for the conductive part and 176 times less ECG electrode gel than the standard commercial wet ECG electrodes. In addition, our electrically small AoP achieved a maximum read range of 142 m and offers a 4 times larger wireless communication range than the typical commercial chip antenna. The adult volunteers’ study results indicated that our system recorded ECG data that correlated well with data from a commercial ECG system and electrodes. Furthermore, in the context of a 12-lead ECG diagnostic system, the fully printed wet ECG electrodes demonstrated a performance similar to that of commercially available wet ECG electrodes while being gentle on the skin. This was confirmed through a blind review method by two cardiology consultants and one family medicine consultant, validating the consistency of the diagnostic information obtained from both electrodes. In conclusion, these findings highlight the potential of fully screen-printed wet ECG electrodes for both monitoring and diagnostic purposes. These electrodes could serve as potential candidates for clinical practice, and the screen-printing method has the capability to facilitate industrial mass production.

“…Wolf–Parkinson–White patients with an ECG of difficult interpretation are common. A normal or at the lower limit (120–130 ms) PR interval may occur due to the presence of a long Kent bundle on the left side with delayed conduction [ 19 ]. A more careful ECG analysis during the screening should have made the suspicion of pre-excitation because of the short PR interval and the delta wave slurring [ 20 ].…”

Sports are a double-edged sword. On the one hand, cardiovascular benefits from sports activity are well-known, and on the other hand, sports may increase the risk of sudden cardiac death (SCD) in subjects with known or unknown cardiovascular diseases. SCD is rare but has a very strong emotional issue. There are many examples involving famous professional athletes, but this is only scratching the surface of a widespread phenomenon that also involves amateur athletes. The importance of safely performing physical activity appears clear in both professional and amateur athletes. In particular, the former undergo a pre-participation screening for SCD primary prevention with different recommendations in each country. On the other hand, a medical examination is not mandatory for non-professional athletes and, therefore, for people who practice sports as an amateur. Widespread distribution of automatic external defibrillators and people trained for cardiopulmonary resuscitation are necessary to promote secondary prevention of SCD. We briefly report a case series of athletes with aborted SCD during sports activity in order to underline and discuss in this review the previously highlighted issues.

“…The sensitivity and specificity of ECG are strong, which is often used to dynamic observation and understand the occurrence of myocardial damage in patients with pneumonia and evaluation of therapeutic effect [4]. Therefore, both the quantitative detection of myocardial enzymes level of serum and the recording technique of ECG in patients have been widely carried out and popularized in hospitals above county level as routine examination items [5]- [11].…”

Pneumonia is a common disease in patients. This paper discusses the signal processing techniques of electrocardiogram (ECG) and the statistical analysis of myocardial enzymes in the diagnosis and treatment of patients with pneumonia and analyzes its significance. Detecting the activity of creatine kinase (CK), isoenzyme (CK-MB), and cardiac troponin T (CTnT) before and after treatment in patients with pneumonia and recording the changes of the electrocardiogram with non-invasive bedside conventional electrocardiogram can be useful for medical diagnosis. In addition, in order to eliminate the ECG signal noise to improve the accuracy of analysis and diagnosis, we have introduced a Butterworth filter to achieve the suppression of interference signals. Moreover, the Butterworth filter method is used to denoise the ECG signal, and the selection of wavelet function, the analysis of noise frequency band, and the threshold processing are solved accordingly. This method has the characteristics of simple calculation and fast processing speed. It can effectively suppress baseline drift noise and improve the overall operation speed. The experimental results show that the proposed method can well filter baseline drift, power frequency interference, EMG interference, and other high-frequency interference in ECG signals, and the real-time performance of the Butterworth filter method in the sampling process has good performance, which provides help for diagnosis. Via comparing and analyzing different ECG signal parameters between the groups, the serum levels of CK, CK-MB, and troponin are demonstrated to be significantly increased with the severity of the disease in patients with pneumonia. Abnormal changes in the ECG indicate that the myocardium may be affected after pneumonia in patients. The detection of CK-MB and troponin levels in the serum of patients with pneumonia has very high sensitivity and specificity. Recording electrocardiogram has good intuitive utility. ECG and myocardial enzyme monitoring are of great significance in the diagnosis and treatment of the development of the disease in patients with pneumonia.
