Panic Attacks: Low Oxygen, Rapid Heartbeat, and Breathing Issues - Cardiology

More Info

Panic attacks can be distressing experiences characterized by sudden episodes of intense fear or discomfort. They often manifest with physical symptoms such as rapid heartbeat, shortness of breath, dizziness, and feelings of impending doom. Your description of experiencing low oxygen levels, rapid heart rate, and sensations of dizziness and numbness aligns with common symptoms of panic attacks, but it is essential to consider both psychological and physiological factors.

From the information provided, it seems you have a history of anxiety and sleep issues, for which you are currently on medication. The episodes you described, where your blood oxygen levels dropped significantly and your heart rate surged, could indeed be related to panic attacks. During a panic attack, the body enters a fight-or-flight response, leading to hyperventilation, which can cause a decrease in carbon dioxide levels in the blood. This can result in symptoms such as lightheadedness, tingling in the extremities, and feelings of suffocation or breathlessness.

The fact that your blood oxygen levels dropped to 70% is concerning, as normal oxygen saturation levels should be between 95% and 100%. While panic attacks can cause temporary changes in breathing patterns, significant drops in oxygen saturation may indicate an underlying respiratory issue or other medical conditions that should be evaluated. It is crucial to discuss these episodes with your healthcare provider, as they can help determine whether further investigations, such as pulmonary function tests or imaging studies, are necessary to rule out any underlying conditions.

Your rapid heart rate (tachycardia) during these episodes is also a common response to panic attacks. The body's sympathetic nervous system is activated, leading to increased heart rate and blood pressure. However, persistent tachycardia or episodes that occur outside of panic attacks should be evaluated by a cardiologist to rule out any cardiac issues.

Given that you have experienced these episodes multiple times in a week, it is advisable to consult with your psychiatrist or mental health professional. They can assess whether your current medication regimen is adequate or if adjustments are needed. Cognitive-behavioral therapy (CBT) is also an effective treatment for panic disorder and can help you develop coping strategies to manage anxiety and panic symptoms.

In summary, while your symptoms may be primarily related to panic attacks, the significant drop in oxygen levels and rapid heart rate warrant further investigation to rule out any underlying medical conditions. It is essential to maintain open communication with your healthcare providers about your symptoms and treatment options. Additionally, practicing relaxation techniques, mindfulness, and gradual exposure to anxiety-provoking situations can help manage panic symptoms and improve your overall quality of life.
