  • He said he felt dizzy and nauseous before passing out on the bathroom floor.

As a cardiac nurse and heart pump specialist, Mark Kader thought he would recognize the signs of a heart attack if he ever had one.

The 41-year-old told Insider that he believes his risk Heart problem He had a low family history of heart problems and exercised regularly. So when he started to feel dizzy and nauseous while doing repairs around the house, he didn’t think it was anything serious.

However, Kader says he collapsed on the bathroom floor and woke up to his wife banging on the door. When she reached home and he passed out, she called an ambulance which arrived shortly after he did.

On the way to the hospital, Kader said his heart rate appeared irregular on the EKG. Given his experience teaching doctors about the same heart pump that ended up saving his life, he kicked himself for not recognizing the early signs of a heart attack.

“I’ve been a cardiac nurse for 15 years, so it’s a shame that I’m putting off the symptoms,” Kader said. “You think it might happen to someone else, but it won’t happen to you.”

In fact, he said, the light head caused an irregular ventricular rhythm (or, arrhythmia). His heart was not working properly to pump blood throughout his body and brain, which is known as cardiogenic shock.

Thinking he was going to throw up, he went into the bathroom and got up on the floor.


Nausea should have been Kadir’s first sign that something was wrong, but he didn’t think his suspicions had anything to do with his heart.

Abiomed – To remove something from his heart. He only needs the device for two and a half days before returning to normal heart function.


While Kader wasn’t sure he had an irregular heartbeat until he saw his own EKG reading, he said it made sense.

Syncopal episodes, or fainting spells, are common symptoms of heart problems, which, like Cader’s case, include arrhythmias and also heart failure.

“It’s the same thing when you have a heart attack,” Kader said of arrhythmia warning signs. “The heart can’t pump blood, so you can get these symptoms too.”


Kader said he regained consciousness and was able to climb into an ambulance with the help of paramedics. As he held his hand, he noticed that it was “profusely sweaty.”

According to him, sweating is another common symptom of heart disease. American Journal of Cardiovascular Disease. Sweating is natural as the heart struggles to pump blood around the body, trying to cool itself down. Still, this symptom can be overlooked when there is no chest pain.

Chest pain

“I didn’t feel like I was in that risk category,” Kader said. But at any time, chest pain, discomfort, nausea, light-headedness, dizziness – it’s worth getting checked out. Because the sooner you know, the better.
