Sensors, Vol. 19, Pages 4495: An Ensemble Learning Approach for Electrocardiogram Sensor Based Human Emotion Recognition Sensors doi: 10.3390/s19204495 Authors: Theekshana Dissanayake Yasitha Rajapaksha Roshan Ragel Isuru Nawinne Recently, researchers in the area of biosensor based human emotion recognition have used different types of machine learning models for recognizing human emotions. However, most of them still lack the ability to recognize human emotions with higher classification accuracy incorporating a limited number of bio-sensors. In the domain of machine learning, ensemble learning methods have been successfully applied to solve different types of real-world machine learning problems which require improved classification accuracies. Emphasising on that, this research suggests an ensemble learning approach for developing a machine learning model that can recognize four major human emotions namely: anger; sadness; joy; and pleasure incorporating electrocardiogram (ECG) signals. As feature extraction methods, this analysis combines four ECG signal based techniques, namely: heart rate variability; empirical mode decomposition; with-in beat analysis; and frequency spectrum analysis. The first three feature extraction methods are well-known ECG based feature extraction techniques mentioned in the literature, and the fourth technique is a novel method proposed in this study. The machine learning procedure of this investigation evaluates the performance of...

Wahid, Anh DinhAbstractAn electrocardiogram (ECG) is used to record the electrical activity of the heart. However, ECG signals are susceptible to the noise from various sources which increases the probability of misinterpretation and can affect the diagnostic process. Traditional noise cancellation techniques, which uses finite and deterministic coefficient, are not efficient, since the ECG signals are non-stationary. Thus, adaptive filters are commonly utilized on such sig...

Study results published this week in the Journal of the American College of Cardiology: Clinical Electrophysiology show that an investigational set of algorithms in Medtronic's Micra transcatheter pacing system (TPS) significantly improves synchrony and cardiac function in patients with impaired electrical conduction between the chambers of the heart, a condition called atrioventricular (AV) block. The results from the MARVEL 2 study are expected to be presented Nov. 16 at the American Heart Association's annual scientific sessions. Medtronic said that based on positive results from both...

The method is based on photoplethysmography (PPG) acquired with the smartphone camera (SPPG). SPPG was compared with the electrocardiogram (ECG), used as the gold standard, and with an external PPG sensor. Twenty-three he...

Conclusions. Our results show that the division of MI diagnoses to STEMI and NSTEMI is not reliable in the Finnish HDR. These diagnoses should not be used as outcomes in scientific research without additional verification from the original ECGs. PMID: 31701776 [PubMed - as supplied by publisher]

CONCLUSION: The results of the present study reveal that varenicline oxalate and varenicline tartrate have similar pharmacokinetic characteristics as varenicline, and that these two formulations exhibit pharmacokinetic equivalence to meet the regulatory criteria. Both varenicline formulations were generally well tolerated.

ConclusionsThe LATER CARD study will provide knowledge on different surveillance modalities for detection of cardiac dysfunction in long-term CCS at risk for heart failure. The results of the study will enable us to improve long-term follow-up surveillance guidelines for CCS at risk for heart failure.

Authors: Ideishi A, Ogawa M, Nagata Y, Idemoto Y, Komaki T, Morii J, Saku K, Miura S Abstract A 30-year-old woman was referred to our hospital to undergo an evaluation for suspected Brugada syndrome. She showed no symptoms, but had a strong family history of sudden cardiac death. During observation, Holter electrocardiography (ECG), which had been performed to investigate her symptoms of occasional dizziness, showed a sinus node dysfunction with an occasional long sinus pause. An implantable cardioverter defibrillator (ICD) was therefore put in place, and bradycardia pacing from the ICD relieved those symptoms duri...

ConclusionsAlthough there is an expanding body of literature on AI and ML in cardiovascular medicine, the future these fields will have in clinical practice remains to be paved. In particular, there is a promising role in providing automated imaging interpretation, automated data extraction and quality control, and clinical risk prediction although these techniques require further refinement and evaluation.
