Wide QRS-T angle is correlated to fatal arrhythmias. The frontal QRS-T angle is the projection of the three-dimensional spatial angle into the frontal plane. This study aimed to develop a sistem that recorded the frontal ECG leads from mice. The frontal QRS-T angle was then derived from those leads. The ECG was acquired by using 3 analog modules which then digitized by microprocessor at 1000 samples/sec. The QRS-T angle calculation was implemented in Matlab to speed up the calculation process. The system was tested to measure a wistar rat of 2 months old. The results showed that QRS angles were quite stable compared to the T angles. Variation in the QRS-T angles was dominated by the T angles. The average QRS-T angle was 31.3° ± 8.04°.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Analog modules,Animal studies,Calculation process,Frontal planes,Independent predictors,Spatial angle,spatial QRS-T angle,Wistar rat[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]animal study,ECG,spatial QRS-T angle,vector cardiogram[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]ACKNOWLEDGMENT We thank the Ministry of Research, Technology and Higher Education of Indonesia for funding provided to this research under Basic Research Grant no. 0001/P3M/E.PE/III/2019.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ISESD.2019.8909639[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
