X Factor star Katie Waissel gave fans an update on her health weeks after she was rushed to the hospital with a 'life-threatening emergency'.
She first posted about the incident two weeks ago in what was believed to be a suspected heart attack.
The 35-year-old took to her social media on Tuesday to provide details on the testing she's undergoing at the hospital.
In the mirror selfie, Katie was hooked up to a monitor with electrodes attached to her chest and ribs.
"Holter Moniter - Cardiac Testing. Currently wearing the Holter Monitor as part of my on going cardiac testing. I will be wearing this device for 48 hours as it records my heart activity," the singer wrote.
"Other testing follows this week, but emotionally I am taking them just one test at a time. Please do know that albeit this is a personal medical issue, I have listened and onboarded so compassionately to your questions and concerns relating to potential causes etc.
She went on to explain that she 'absolutely intends' to share the results of the tests with her fans and 'hope to either give you clarity or peace of mind, to those that are seeking it.'
"Until then, we must try to onboard an objective mindset and focus on staying healthy, safe and warm," Katie added. "I appreciate you all so greatly, and thank you for kindly embracing this discovery process with me."
The star was taken to the hospital two weeks ago and thanked the NHS as well as ambulances for their services.
She was told that there would be a wait for the ambulance but it showed up at her door within minutes.
"The entire team at Watford were / are beyond impeccable, and I am so grateful for your continued help!!" she said at the time.
Fans took to the comment section of her latest Instagram post to show their support for the star.

"Amazing how transparent you are being. You don't owe anyone anything, but the fact you are sharing this journey is hugely appreciated x," one impressed fan commented.
Another added: "Sending love to you sweetie," while others simply posted heart and heart eyes emojis.
Katie is one of a number of X Factor stars who went back to normal jobs after finding fame on the show.
The former receptionist was one of the standout stars of her season after making it through to the live shows, but ended up being eliminated in the quarter final.
Rumoured plans to join Jay Z's record label never materialised, but Katie went on to release an album and join new band Red Velvet Lovers.
