One day, I received a call from my mother who was concerned about my dad as he was feeling unwell and increasingly uncomfortable with some heartburn. She was very worried and asked me to come as she was calling an ambulance.
As soon as I got to their place, I could see that my father was struggling. He was uncomfortable and had been feeling this way for a few days. Within a few minutes, the paramedics came and identified an issue on his ECG. He was told to go to the hospital with them and my mother was becoming anxious.
