I was diagnosed with Arrhythmia way back 2023 because of having low potassium and magnesium. My heart skips a beat every 3 seconds and does a flatline for straight 2-5 seconds sometimes. The longest is 5 seconds the shortest is 3 seconds. Then it beats back again.
My heart is also in pain and swollen before, it grows large when I was 9 years old. Due to nonstop crying—so I was advised by my doctor that when you cry, do not keep it inside. Instead, shout. Cry loudly. Do not hurt your heart, it is already in pain when you cry silently. And a lot of people does that.
