Largest ECG screening program in the United States and recognized internationally as a leader in screening for conditions that can cause Sudden Cardiac Death (SCD). Performed over 335,000 FREE ECGs to high school and college students since 2006 and have identified more than 3,575 young adults with previously undiagnosed cardiac conditions.

2021年11月11日 · Here we report the synthesis of the phase and determine its superconducting transition with maximum at 155 GPa. The decrease in critical temperature under an external magnetic field suggests the upper critical magnetic field of about 14–22 T at megabar pressures consistent with theoretical data.
